                       consolidated financial statements.


5SILICON STORAGE TECHNOLOGY, INC. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS AT MARCH 31, 2005 (UNAUDITED):


1. Basis of Presentation
In the opinion of management, the accompanying unaudited condensed interim consolidated
financial statements contain all adjustments, all of which are normal and recurring in nature,
necessary to fairly state our financial position, results of operations and cash flows. The results
of operations for the interim periods presented are not necessarily indicative of the results that
may be expected for any future interim periods or for the full fiscal year. These interim financial
statements should be read in conjunction with the consolidated financial statements in our Annual
Report on Form 10-K for the year ended December 31, 2004.
The year-end balance sheet at December 31, 2004 was derived from audited financial statements,
but does not include all disclosures required by generally accepted accounting principles. Please
refer to the audited financial statements in our Annual Report on Form 10-K for the year ended
December 31, 2004.

Reclassifications:
Certain amounts in our prior years consolidated financial statements have been
reclassified to conform to the current year presentation. These reclassifications have no impact on
our previously reported results of operations or shareholders' equity. Specifically, we reclassified
certain auction rate securities from cash equivalents to short-term investments where interest rates
reset in less than 90 days but have a maturity date longer than 90 days. This resulted in a
reclassification from cash and cash equivalents to short-term investments of $40.4 million at
December 31, 2003 and $10.5 million at March 31, 2004. The reclassification in both periods had the
effect of decreasing net cash used in investing activities by $29.9 million for the three months
ended March 31, 2004.

Recent Accounting Pronouncements
In December 2004, the FASB issued SFAS 123R (revised 2004), or SFAS 123R, "Share Based
Payment." SFAS 123R is a revision of FASB 123 and supersedes APB No. 25. SFAS 123R establishes
standards for the accounting for transactions in which an entity exchanges its equity instruments
for good or services or incurs liabilities in exchange for goods or services that are based on the
fair value of the entity's equity instruments. SFAS 123R focuses primarily on accounting for
transactions in which an entity obtains employee services in share-based payment transactions. SFAS
123R requires an entity to measure the cost of employee services received in exchange for an award
of equity instruments based on the grant-date fair value of the award over the period during which
an employee is required to provide service for the award. The grant-date fair value of employee
share options and similar instruments must be estimated using option-pricing models adjusted for the
unique characteristics of those instruments unless observable market prices for the same or similar
instruments are available. In addition, SFAS 123R requires a public entity measure the cost of
employee services received in exchange for an award of liability instruments based on its current
fair value and that the fair value of that award will be remeasured subsequently at each reporting
date through the settlement date. In April 2005, the U. S. Securities and Exchange Commission
adopted a new rule that amends the compliance dates of SFAS 123R. The effective date of SFAS 123R
for us is for the first interim period of 2006. Although we have not yet determined whether the
adoption of SFAS 123R will result in amounts that are similar to the current pro forma disclosures
under SFAS123, we are evaluating the requirements under SFAS 123R and expect the adoption to have a
significant adverse impact on our consolidated operating expenses.
In March 2005, the FASB issued FSP No. 46R-5, "Implicit Variable Interests under FASB
Interpretation No. 46 (revised December 2003), Consolidation of Variable Interest Entities", or
FSP46R-5, which provides guidance for a reporting enterprise on whether it holds an implicit
variable interest in a variable interest entity (VIE) or potential VIE when specific conditions
exist. FSP46R-5 is effective the first period beginning after March 3, 2005 and, accordingly, is
being adopted by us as of April 1, 2005. We are currently evaluating the effect that the adoption of6FSP46R-5 will have on our consolidated results of operations and financial condition but do not
expect it to have a material impact.

2. Computation of Net Income (Loss) Per Share
We have computed and presented net income (loss) per share under two methods, basic and
diluted. Basic net income (loss) per share is computed by dividing net income (loss) by the weighted
average number of common shares outstanding for the period. Diluted net income (loss) per share is
computed adjusting the net income (loss) by the potential minority interests and dividing by the sum
of the weighted average number of common shares outstanding and potential common shares (when
dilutive). A reconciliation of the numerator and the denominator of basic and diluted net income
(loss) per share is as follows (in thousands, except per share amounts):

Anti-dilutive stock options to purchase 1,715,000 shares of common stock were outstanding as of
March 31, 2004 with a weighted average exercise price of $12.12. These stock options were not
included in the computation of diluted net income per share for the three months ended March 31,
2004 because the exercise price of these options exceeded the average fair market value of our
common stock for the three months ended March 31, 2004. Stock options to purchase 10,605,000 shares
of common stock were outstanding as of March 31, 2005 with a weighted average exercise price of
$8.09. These stock options were not included in the computation of diluted net loss per share for the
three months ended March 31, 2005 because we had a net loss for this period.

7Stock Compensation:
We account for stock-based compensation using the intrinsic value method. No compensation
cost has been recognized for the stock option plans or the employee stock purchase plan. Had
compensation cost for these plans been determined based on the fair value at the grant date for the
awards, our net income (loss) and net income (loss) per share for the three months ended March 31,
2004 and 2005 would have been as follows, respectively:

The fair value of each option grant for both our 1995 Equity Incentive Plan and our 1995
Non-Employee Directors' Stock Plan is estimated on the date of grant using the Black-Scholes multiple
options pricing model with the following weighted average assumptions for the three months ended
March 31, 2004 and 2005, respectively:

The fair value of each stock purchase right under our 1995 Employee Stock Purchase Plan, or the
Purchase Plan, is estimated on the date of grant using the Black-Scholes multiple options pricing
model with the following weighted average assumptions for the three months ended March 31, 2004 and
2005, respectively:

The weighted average valuation of right grants under the Purchase Plan during the three months
ended March 31, 2004 and 2005 was $5.20 and $3.90, respectively.

8Option grants and Purchase Plan rights are priced at the date of grant. The risk-free interest
rate range represents the low and high end of the range used at different points during the
period.

3. Investments
We consider cash and all highly liquid investments purchased with an original or remaining
maturity of less than three months at the date of purchase to be cash equivalents. Substantially all
of our cash and cash equivalents are in the custody of three major financial institutions.
Short and long-term investments, which are comprised of federal, state and municipal government
obligations, foreign and public corporate debt securities and listed equity securities, are
classified as available-for-sale and carried at fair value, based on quoted market prices, with the
unrealized gains or losses, net of tax, reported in Shareholders' Equity as Other Comprehensive
Income. The cost of debt securities is adjusted for amortization of premiums and accretion of
discounts to maturity, both of which are included in interest income. Realized gains and losses are
recorded on the specific identification method. Realized gains and realized losses for the three
months ended March 31, 2004 and 2005 were not material.
King Yuan Electronics Company Limited, or KYE, Insyde Software Corporation, or Insyde, Powertech
Technology, Incorporated, or PTI, and Professional Computer Technology Limited, or PCT, are
Taiwanese companies that are listed on the Taiwan Stock Exchange. Investments in these companies
have been included in "Long-term available-for-sale investments." The investment not available for
resale due to local securities regulations within one year at the balance sheet date is recorded at
the investment cost. The investment available for resale within one year at the balance sheet date
is recorded at fair market value, with unrealized gains and losses, net of tax, reported in
Shareholders' Equity as Other Comprehensive Income. If a loss is other than temporary, it is
reported as an "Impairment of equity investments." Cash dividends and other distributions of
earnings from the investees, if any, are included in other income when declared.

The fair values of available-for-sale investments as of March 31, 2005 were as follows (in
thousands):

Contractual maturity dates of our available-for-sale investments range from 2005 to 2033.  All of the securities are
classified as current as they are expected to be realized in cash or sold or consumed during the normal operating cycle

Inventories are stated at the lower of cost, determined on a first-in, first-out basis, or market
value. We typically plan our production and inventory levels based on internal forecasts of customer
demand, which are highly unpredictable and can fluctuate substantially. The value of our inventory
is dependent on our estimate of future average selling prices, and, if our projected average selling
prices are over estimated, we may be required to adjust our inventory value to reflect the lower of
cost or market. Due to the large number of units in our inventory, even a small change in average
selling prices could result in a significant adjustment and have a material impact on our financial
position and results of operations. Our inventories include high technology parts and components
that are specialized in nature or subject to rapid technological obsolescence. Some of our customers
have requested that we ship them product that has a finished goods date of manufacture that is less
than one year old. In the event that this becomes a common requirement, it may be necessary for us
to provide for an additional allowance for our on-hand finished goods inventory with a date of
manufacture of greater than one year old, which could result in a material adjustment and could harm
our financial results. We review on-hand inventory including inventory held at the logistic center
for potential excess, obsolete and lower of cost or market exposure and adjust the level of
inventory reserve accordingly.

As of March 31, 2005, our allowance for excess and obsolete inventories includes an allowance for
our on-hand finished goods inventory with a date of manufacture of greater than two years old and
for certain products with a date of manufacture of greater than one year old. In addition, our
allowance includes an allowance for die, work-in-process10and finished goods that exceed our
estimated forecast for the next twelve to twenty four months. For the obsolete inventory analysis, we
review inventory items in detail and consider date code, customer base requirements, known product
defects, planned or recent product revisions, end of life plans and diminished market demand. For
excess inventory analysis, we review inventory items in detail and consider our customer base
requirements and market demand. While we have programs to minimize the required inventories on hand
and we consider technological obsolescence when estimating allowances for potentially excess and
obsolete inventories and those required to reduce recorded amounts to market values, it is
reasonably possible that such estimates could change in the near term. Such changes in estimates
could have a material impact on our financial position and results of operations.

Our products are generally subject to warranty and we provide for the estimated future costs of
repair, replacement or customer accommodation upon shipment of the product in the accompanying
statements of operations. Our warranty accrual is estimated based on historical claims compared to
historical revenues and assumes that we have to replace products subject to a claim. For new
products, we use our historical percentage for the appropriate class of product. The increase in the
consumption of the reserve for the three months ended March 31, 2005 as compared to the comparable
period of the prior year relates mainly to the rescreening work related to two specific customers,
which was reserved for as of December 31, 2004. The total estimated reserve for this rescreening
work was reevaluated based on updated information at the end of first quarter of 2005, which
decreased provisions for warranty by $500 thousand for the three month period ended March 31,
2005.


5. Commitments
During 2001 and the second quarter of 2004, we recorded a period charge to other operating
expense of $756 thousand and $1.5 million, respectively, relating to operating leases for unoccupied
buildings. These charges represent the fair value of the liability determined by reducing the
remaining lease commitment by the estimated sublease income relating to these two buildings. The
estimated liability may be adjusted subsequently depending on the actual sublease income we may
receive. At December 31, 2004 and March 31, 2005, payments made have reduced the recorded liability
to $976 thousand and $636 thousand, respectively.

11Our technology license agreements generally include an indemnification clause that indemnifies
the licensee against liability and damages (including legal defense costs) arising from any claims
of patent, copyright, trademark or trade secret infringement by our proprietary technology. The
terms of these guarantees approximate the terms of the technology license agreements, which
typically range from five to ten years. Our current license agreements expire from 2005 through
2014. The maximum possible amount of future payments we could be required to make, if such
indemnifications were required on all of these agreements, is $39.7 million. We have not recorded
any liabilities as of March 31, 2005 related to these indemnities as no such claims have been made
or asserted.

During our normal course of business, we have made certain indemnities, commitments and
guarantees under which we may be required to make payments in relation to certain transactions.
These include indemnities to various lessors in connection with facility leases for certain claims
arising from such facility or lease, and indemnities to our directors and officers to the maximum
extent permitted under the laws of California. In addition, we have contractual commitments to some
customers, which could require us to incur costs to repair an epidemic defect with respect to our
products outside the normal warranty period if such defect were to occur. The duration of these
indemnities, commitments and guarantees varies. The majority of these indemnities, commitments and
guarantees do not provide for any limitation of the maximum potential future payments that we could
be obligated to make. We have not recorded any liability for these indemnities, commitments and
guarantees in the accompanying condensed consolidated balance sheets. We do, however, accrue for
losses for any known contingent liability, including those that may arise from indemnification
provisions, when future payment is probable and the amount is reasonably estimatable.

6. Contingencies
In January 1996, Atmel Corporation filed suit against SST alleging that we infringed six U.S.
patents. We successfully moved for summary judgment on two of the six asserted patents in September
1997. In January 2001, Atmel withdrew its allegation that we infringed another patent. On May 7,
2002, a judgment was entered against us in the amount of $36.5 million based on a jury's finding
that we infringed two of the three remaining patents. We appealed the judgment on July 16, 2002. On
September 12, 2003 the Court of Appeals upheld the jury's verdict. On November 18, 2003 the Court of
Appeals denied our request for a rehearing, and in December 2003 we paid Atmel $37.8 million to
satisfy the judgment plus statutory interest accrued during the appeals. The payment was recorded as
other operating expense in the year ending December 31, 2003. In addition, on June 28, 2004 we paid
$247 thousand of legal related expenses incurred by Atmel pursuant to the court order.
The third patent remaining in the case, the '903 patent, expired in September 2001. The trial
court has held that, if it is found to be valid, certain of our products infringed that patent. The
trial to determine whether the '903 patent is invalid began on July 29, 2002. On August 5, 2002
the jury announced that it was unable to reach a verdict on our
invalidity defense, and a mistrial was declared. Atmel requested a new trial,
but the Court stayed the matter until after our appeal of the earlier judgment is resolved. At
Atmel's request, the Court has directed the parties to conduct a settlement conference before a
Magistrate Judge. That settlement conference was scheduled for April 14, 2004 and was subsequently
rescheduled for September 7, 2004. No conclusion was reached during the settlement conference on
September 7, 2004. A new trial date on the invalidity of the '903 patent has been scheduled for
August 1, 2005. The impact related to the outcome of the remaining patent is undeterminable at this
time.

In January and February 2005, multiple putative shareholder class action complaints were filed
against SST and certain of our directors and officers, in the United States District Court for the
Northern District of California, following our announcement of anticipated financial results for the
fourth quarter of 2004. The complaints are captioned: Hunt v. Silicon Storage Technology, Inc.,
et al., Case No. C 05 00408 WHA (N.D. Cal.); Baker v. Silicon Storage Technology, Inc., et
al., Case No. C 05 00295 PJH (N.D. Cal.); Grobler v. Silicon Storage Technology, Inc., et
al., Case No. C 05 00376 MHP (N.D. Cal.); Talmo v. Silicon Storage Technology, Inc., et
al., Case No. C 05 00390 MMC (N.D. Cal.); and DiCintio v. Silicon Storage Technology, Inc.,
et al., Case No. C 05 0708 MMC (N.D. Cal.). The complaints seek unspecified damages on alleged
violations of federal securities laws during the period from March 22, 2004 to December 20, 2004.
Consolidation and the appointment of lead plaintiff are currently pending in these purported class
actions. We intend to take all appropriate action in response to these lawsuits. The impact related
to the outcome of these matters is undeterminable at this time.

12In January and February 2005, following the filing of the putative class actions, multiple
shareholder derivative complaints were filed in California Superior Court for the County of Santa
Clara, purportedly on behalf of SST against certain of our directors and officers. The factual
allegations of these complaints are substantially identical to those contained in the putative
shareholder class actions filed in federal court. The derivative complaints assert claims for, among
other things, breach of fiduciary duty and violations of the California Corporations Code. These
derivative actions have been consolidated under the caption In Re Silicon Storage Technology,
Inc. Derivative Litigation, Lead Case No. 1:05CV034387 (Cal. Super. Ct., Santa Clara Co.). We
intend to take all appropriate action in response to these lawsuits. The impact related to the
outcome of these matters is undeterminable at this time.

From time to time, we are also involved in other legal actions arising in the ordinary course of
business. We have accrued certain costs associated with defending these matters. There can be no
assurance the remaining Atmel complaint, the shareholder class action complaints, the shareholder
derivative complaints or other third party assertions will be resolved without costly litigation, in
a manner that is not adverse to our financial position, results of operations or cash flows or
without requiring royalty payments in the future which may adversely impact gross margins. No
estimate can be made of the possible loss or possible range of loss associated with the resolution
of these contingencies. As a result, no losses have been accrued in our financial statements as of
March 31, 2005.

7. Line of Credit
On July 16, 2004, we entered into a 2-year loan agreement with Cathay Bank, a U.S. bank,
for a $3.0 million revolving line of credit.  The interest rate for the line of credit is 3.475% per
annum.  The line of credit is collateralized by a $3.0 million certificate of deposit which is
included in non-current other assets.  The certificate of deposit matures in July 2006 and carries
an interest rate of 2.6% per annum.  As of March 31, 2005, we have borrowed $1.0 million under our
line of credit which is included in other liabilities.  As of December 31, 2004, there were no
borrowings under our line of credit.


8. Acquisitions

Emosyn LLC. On September 10, 2004, we consummated the
acquisition of an 83.6% ownership of privately held Emosyn LLC, or Emosyn, for an aggregate cash
purchase price of approximately $16.0 million including costs related to the acquisition. Emosyn is
a fabless semiconductor manufacturer specializing in the design and marketing of smart card ICs for
subscriber identification module, or SIM, card applications. We believe that the acquisition will
help Emosyn leverage our foundry relationships and manufacturing operation infrastructure in order
to meet the rising demand for Emosyn's smart card products. The acquisition also provides us the
opportunity to establish SuperFlash technology as the technology-of-choice in the strategically
important smart card products. The acquisition was accounted for under the purchase method of
accounting, and accordingly, the net assets and results of operations of the acquired business were
included in the consolidated financial statements from the date of acquisition.

In connection with the Emosyn acquisition, we issued the minority stockholder
a put option. On the fourth anniversary date of the closing of the acquisition or if there is an
earlier material change in business, the minority stockholder shall have the right to require SST to
purchase all of its interest at the then current fair market value of the minority interest fair
market value stock price. Refer to note 14 for additional information.

13The total purchase price was allocated to the estimated fair value of the assets
acquired and liabilities assumed as follows (in thousands):

We valued the existing technology and in-process research and development, or IP R&D, utilizing
a discounted cash flow model which uses forecasts of future revenues and expenses related to the
intangible asset.  We utilized a discount rate of 30% for existing technology, trade name and
customer relationships, 50% for in-process research and development, and 18% for backlog,
respectively.  The existing technology and trade name are amortized to cost of revenues over their
estimated lives of five years.  The customer relationships and backlog are amortized to cost of
revenues over their estimated lives of one to three years.  As of March 31, 2005, existing
technology, trade name, customer relationships and backlog are all included in intangible
assets.

In-process research and development acquired of $2.0 million was expensed and
included in other operating expenses as of the date of the acquisition.

G-Plus, Inc.  On November 5, 2004, we purchased substantially all the assets of
G-Plus Inc., or G-Plus, a privately held company located in Santa Monica, California.  The
acquisition was accounted for under the purchase method of accounting, and accordingly, the net
assets and results of G-Plus' operations have been included in the consolidated financial statements
since that date.  G-Plus is a fabless semiconductor manufacturer specializing in the design and marketing of
radio frequency ICs and monolithic microwave ICs for a wide range of wireless and multimedia
applications.  The acquisition provides us the opportunity to make SuperFlash the embedded memory of
choice for wireless applications.  We also believe that the acquisition will help G-Plus leverage
our foundry relationships and manufacturing operation infrastructure in order to meet the rising
demand for G-Plus wireless products.The aggregate purchase price was $26.9 million, including $4.6 million of cash, common stock valued
at $22.1 million and costs related to the acquisition of $200 thousand.  The fair value of the
3,030,082 shares of our common stock issued to G-Plus was determined
based on the average closing price of our common stock over a two-day trading period prior
to the closing date.  Below is a summary of the total preliminary purchase price (in thousands):Cash..............................................................  $    4,600

We valued the existing technology and in-process research and development, or IP R&D, utilizing
a discounted cash flow model which uses forecasts of future revenues and expenses related to the
intangible asset.  We utilized a discount rate of 28% for existing technology and customer
relationships, 30-35% for in-process research and development projects, and 26% for backlog,
respectively.  The existing technology is amortized to cost of revenues over its estimated life of
four years.  The customer relationships and backlog are amortized to cost of revenues over their
estimated lives of one to three years.  As of March 31, 2005, existing technology, customer
relationships and backlog are all included in intangible assets.

In-process research and development acquired of $3.9 million was expensed and
included in other operating expenses as of the date of the acquisition.

9. Goodwill and Intangible Assets:
As discussed in note 8, our acquisitions of Emosyn and G-Plus included the acquisition of
$10.6 million of finite-lived intangible assets. The acquisition of G-Plus also included the
acquisition of $15.6 million of goodwill. The goodwill is not being amortized, but is tested for
impairment annually, as well as when an event or circumstance occurs indicating a possible
impairment in value.

15As of March 31, 2005, our intangible assets consisted of the following (in thousands):

All intangible assets are being amortized on a straight-line method over their estimated useful
lives. Existing technologies have been assigned useful lives of between four and five years (with a
weighted average life of approximately 4.8 years). Trade names, customer relationships and backlogs
have been assigned useful lives of five years, three years and one year, respectively.

10. Segment Reporting
Our operations involve the design, development, manufacturing, marketing and technical
support of our nonvolatile memory technology and products. We offer low to medium density devices
that target a broad range of existing and emerging applications in the digital consumer, networking,
wireless communications and Internet computing markets. Our products are differentiated based upon
attributes such as density, voltage, access speed, package and predicted endurance. We also license
our technology for use in non-competing applications.
We manage our business in six reportable segments: the Standard Memory Product Group, or SMPG,
the Application Specific Product Group, or ASPG, the Special Product Group, or SPG, the Emosyn
Products, or Emosyn, the SST Communications Corporation Products, or SCC, and Technology Licensing.
We do not allocate operating expenses, interest and other income, interest expense, impairment of
equity investments and provision for or benefit from income taxes to any of these segments for
internal reporting purposes, as we do not believe that allocating these expenses are material in
evaluating a business unit's performance.

16SMPG includes our standard flash memory product families: the Multi-Purpose Flash, or MPF, family
and the Multi-Purpose Flash Plus, or MPF+, family. These product families allow us to produce
products optimized for cost and functionality to support a broad range of mainstream applications
that use nonvolatile memory products.
ASPG includes Concurrent SuperFlash, Serial Flash, Firmware Hub, or FWH, and Low Pin Count, or
LPC, flash products. These products are designed to address specific applications such as cellular
phones, hard disk drives and PCs. ASPG also includes flash embedded controllers such the ATA flash
disk controller to consumer, industrial and mass data storage applications.
SPG includes ComboMemory, ROM/RAM Combos, the Small Sector Flash, or SSF, family, Multi-Time
Programmable, or MTP, family, FlashFlex51 microcontrollers and other special flash products. These
products are used in applications requiring low power and a small form factor such as cellular
phones, wireless modems, MP3 players, pagers and personal digital organizers.Emosyn includes flash memory based microprocessor chips. The
Theseus Platinum product family specifically targets the smart card market through the sales of the
TP-40, TP-62, TP-100 and TP-130 products. These products are used primarily in cell phone
applications, and include such benefits of use as lower power consumption, long term data retention
and high endurance of data access. We acquired a majority ownership of Emosyn LLC on September 10,
2004. The segment data is reflected from this date forward.

SCC includes RF transmitter, receiver, synthesizer, power amplifier and
switch products. These products provide end-to-end RF solutions to enable wireless multimedia and
broadband networking applications. We formed SST Communications Corporation and acquired the
operations of G-Plus, Inc. on November 5, 2004. The segment data is reflected from this date
forward.

Technology Licensing includes both license fees and royalties.
The following table shows our product revenues and gross profit (loss) for each segment (in
thousands):

Professional Computer Technology Limited, or PCT, earns commissions for point-of-sales
transactions to its customers. PCT's commissions are paid at the same rate as all of our other
stocking representatives in Asia. In addition, we pay Silicon Professional Technology Ltd., or SPT,
a wholly-owned subsidiary of PCT, a fee for providing logistics center functions. This fee is based
on a percentage of revenue for each product shipped through SPT to our end customers. The fee paid
to SPT covers the costs of warehousing and insuring inventory and accounts receivable, the personnel
costs required to maintain logistics and information technology functions and the costs to perform
demand forecasting, billing and collection of accounts receivable.


1813. Income Taxes
We determined that based upon our historical losses and other available objective evidence
that there is sufficient uncertainty regarding the realizability of our deferred tax assets such
that a full valuation allowance was required. Accordingly, we maintain a valuation allowance against
our deferred tax assets at March 31, 2005. Our provision for the three months ended March 31, 2005
is related to foreign withholding and tentative minimum tax.

14. Subsequent Events
Actrans Systems Inc. On April 11, 2005, we entered into a Share Purchase Agreement to
acquire all of the outstanding capital stock of Actrans Systems Inc., or Actrans, a company
incorporated and existing under the laws of the Republic of China. Pursuant to the terms of the
Share Purchase Agreement, we agreed to issue 4,358,255 shares of our Common Stock and approximately
$4.9 million in cash to the shareholders of Actrans. On April 11, 2005, at the initial closing of
the acquisition, 4,241,359 of the shares were issued and approximately $4.8 million in cash was
paid. The remaining 116,896 shares of our Common Stock will be issued and approximately $131
thousand in cash will be paid, after the receipt of necessary approvals from the Hsinchu
Science-Based Industry Park Administration of the Republic of China.
Emosyn. On April 15, 2005, we acquired the remaining minority interest of Emosyn for $3.1
million in cash, making Emosyn a wholly-owned subsidiary.

19Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations.
The following discussion may be understood more fully by reference to the consolidated
financial statements, notes to the consolidated financial statements, and management's discussion
and analysis of financial condition and results of operations contained in our Annual Report on Form
10-K for the year ended December 31, 2004, as filed with the Securities and Exchange Commission.
The following discussion contains forward-looking statements, which involve risk and
uncertainties. All forward-looking statements included in this document are based on information
available to us on the date hereof, and we assume no obligation to update any such forward-looking
statements. Our actual results could differ materially from those anticipated in these
forward-looking statements as a result of certain factors which are difficult to forecast and can materially
affect our quarterly or annual operating results. Fluctuations in revenues and operating results may
cause volatility in our stock price. Please refer to the section below entitled "Business
Risks."
Overview
We are a leading supplier of flash memory semiconductor devices for the digital consumer,
networking, wireless communication and Internet computing markets.
The semiconductor industry has historically been cyclical, characterized by periodic changes in
business conditions caused by product supply and demand imbalance. When the industry experiences
downturns, they often occur in connection with, or in anticipation of, maturing product cycles and
declines in general economic conditions. These downturns are characterized by weak product demand,
excessive inventory and accelerated decline of selling prices. In some cases, downturns, such as the
one we experienced from late 2000 through 2002, lasted for more than a year. We began to experience
a slow recovery during 2002 through the first half of 2003. During the second half of 2003 and the
first half of 2004, demand for our products increased sharply and we began to see improvements in
the average selling prices of our products. However, we experienced a decrease in the average
selling prices of our products as a result of the industry-wide oversupply and excessive inventory
in the market in the second half of 2004 and the first quarter of 2005. Our business could be
further harmed by industry-wide prolonged downturns in the future.
Our product sales are made primarily using short-term cancelable purchase orders. The quantities
actually purchased by the customer, as well as shipment schedules, are frequently revised to reflect
changes in the customer's needs and in our supply of product. Accordingly, our backlog of open
purchase orders at any given time is not a meaningful indicator of future sales. Changes in the
amount of our backlog do not necessarily reflect a corresponding change in the level of actual or
potential sales.
We derived 90.0%, 86.0% and 82.7% of our net product revenues during 2003, 2004 and the three
months ended March 31, 2005, respectively, from product shipments to Asia. Additionally,
substantially all of our wafer suppliers and packaging and testing subcontractors are located in
Asia.
Our top ten end customers, excluding transactions through stocking representatives and
distributors, accounted for 37.7%, 29.1% and 33.4% of our net product revenues in 2003, 2004 and the
three months ended March 31, 2005, respectively.
No single end customer, which we define as original equipment manufacturers, or OEMs, original
design manufacturers, or ODMs, contract electronic manufacturers, or CEMs, or end users, represented
10.0% or more of our net product revenues during 2003, 2004 or the three months ended March 31,
2005.
Since 2001, we have been out-sourcing activities for our customer service logistics to support
our customers. Currently Silicon Professional Technology Ltd., or SPT, supports our customers in
Taiwan, China and other Southeast Asia countries. SPT provides planning, warehousing, delivery,
billing, collection and other logistic functions for us in these regions. SPT is a wholly-owned
subsidiary of one of our stocking representatives in Taiwan, Professional Computer Technology
Limited, or PCT. Please see a description of our relationship with PCT under "Item 7. Management's
Discussion and Analysis of Financial Condition and Results of Operations - Related Party
Transactions" in our Annual Report on Form 10-K for the year ended December 31, 2004. Products20shipped to SPT are accounted for as our inventory held at our logistics center, and revenue is
recognized when the products have been delivered and are considered as a sale to our end customers
by SPT. For the year ended December 31, 2003 and 2004 and the three months ended March 31, 2005, SPT
serviced end customer sales accounting for 64.2%, 52.9% and 51.3%, respectively, of our net product
revenues recognized. As of December 31, 2004 and March 31, 2005, SPT represented 55.1% and 47.6% of
our net accounts receivable, respectively.

We ship products to, and have accounts receivable from, OEMs, ODMs, CEMs, stocking
representatives, distributors, and our logistics center. Our stocking representatives, distributors
and logistics center reship our products to our end customers, including OEMs, ODMs, CEMs and end
users. Shipments, by us or our logistic center, to our top three stocking representatives for
reshipment accounted for 29.9%, 34.0% and 33.7% of our product shipments in 2003, 2004 and the three
months ended March 31, 2005, respectively. In addition, the same three stocking representatives
solicited sales, for which they received a commission, for 32.8%, 25.1% and 21.8% of our shipments
to end users in 2003, 2004 and the three months ended March 31, 2005, respectively.

Critical Accounting Estimates
For information related to our revenue recognition and other critical accounting estimates,
please refer to the "Critical Accounting Estimates" section of "Management's Discussion and Analysis
of Financial Condition and Results of Operations" contained in our Annual Report on Form 10-K for
the year ended December 31, 2004.
Results of Operations: Quarter Ended March 31, 2005
Net Revenues
Net revenues were $86.3 million for the first quarter of 2005 as compared to $104.1 million
in the fourth quarter of 2004 and $104.4 million for the first quarter of 2004. Net revenues
decreased compared to the fourth quarter of 2004 due to a decrease in unit shipment and average
selling prices. Net revenues decreased compared to the first quarter of 2004 due to decreased
average selling prices for our products and decreased technology license revenue, offset by
increased unit shipments.
Product Revenues. Product revenues were $79.3 million in the first quarter of 2005 as
compared to $96.5 million in the fourth quarter of 2004 and $91.4 million in the first quarter of
2004. Net revenues decreased compared to the fourth quarter of 2004 due to a decrease in unit
shipment and average selling prices. The industry-wide oversupply and continued heavy competition
caused a decrease in our blended average selling price of our products of 6.6%. Unit shipments
decreased 11.6% from the fourth quarter of 2004 to the first quarter of 2005 as a result of weaker
than expected demand in wireless communications and Internet computing segments. In particular,
shipments to the smart card IC market decreased 41.7% after achieving record shipments in the fourth
quarter of 2004. Product revenues decreased compared to the first quarter of 2004 due to decreased
average selling prices for our products of 24.6% offset by increased unit shipments of 15.6%. Unit
shipments fluctuate due to overall industry supply and demand.
Technology Licensing Revenues. Revenues from license fees and royalties were $7.0 million
in the first quarter of 2005, as compared to $7.5 million in the fourth quarter of 2004 and $13.1
million in the first quarter of 2004. Revenues from license fees and royalties are recognized upon
the licensees' acceptance of the delivery of our engineering milestones. The decease in revenue in
the first quarter of 2005 compared to the first quarter of 2004 is due to higher license fees from
new licensees in the first quarter of 2004. Revenues from technology licensing fluctuate upon the
timing of the delivery of engineering milestones. We anticipate that revenues from technology
licensing may fluctuate significantly in the future.

Gross Profit
Gross profit was $12.6 million, or 14.6% of net revenues, in the first quarter of 2005 as
compared to gross profit of $603 thousand, or 0.6% of net revenues, in the fourth quarter of 2004
and $38.2 million, or 36.5% of net revenues, in the first quarter of 2004. The increase in gross
profit from the fourth quarter of 2004 to the first quarter of 2005 is primarily due to the
provision for inventory and adverse purchase commitments of $27.8 million in the fourth quarter of
2004 versus the provision for inventory and adverse purchase commitments of $10.8 million in the21first quarter of 2005. This is offset by decreased average selling prices of our products of 6.6%,
an 11.6% decrease in unit shipments and decreased license revenues of $489 thousand. The decrease in
gross profit in the first quarter of 2005 when compared to the first quarter of 2004 is due
primarily to increased provision for inventory and adverse purchase commitments and decreases in
average selling prices in the first quarter of 2005 offset by increases in unit shipments. Product
gross margin was 7.0% for the first quarter of 2005, compared to negative 7.2% for the fourth
quarter of 2004 and 27.5% for the first quarter of 2004. The increase in product gross margin from
the fourth quarter of 2004 to the first quarter of 2005 primarily relates to the inventory reserves
provided. The decrease in product gross margin from the first quarter of 2004 to the first quarter
of 2005 relates to decreased average selling prices of our products by 24.6%. For other factors
affecting our gross profit, please also see "Business Risks - We incurred significant inventory
valuation adjustments in 2003, 2004 and the first quarter of 2005 and we may incur additional
significant inventory valuation adjustments in the future."
Operating Expenses
Our operating expenses consist of research and development, sales and marketing, and general
and administrative expenses. Operating expenses were $26.0 million, or 30.1% of net revenues, in the
first quarter of 2005, compared to $27.9 million, or 26.8% of net revenues, in the fourth quarter of
2004, and $22.7 million, or 21.8% of net revenues, in the first quarter of 2004. The decrease of
$1.9 million from the fourth quarter of 2004 was primarily due to the write off of $4.2 million of
in-process research and development related to the acquisition of G-Plus in the fourth quarter of
2004 and a decrease of $756 thousand in the first quarter of 2005 related to bad debt provision,
offset by increased headcount related expenses of $2.2 million and general and administrative
related outside services of $961 thousand. The increase of $3.3 million from the first quarter of
2004 was primarily due to increased outside services of $2.0 million and headcount related expenses
of $1.1 million. We anticipate that we will continue to devote substantial resources to research and
development, sales and marketing and general and administrative, and that these expenses may
increase in dollars.
Research and development. Research and development expenses include costs associated with
the development of new products, enhancements to existing products, quality assurance activities and
occupancy costs. These costs consist primarily of employee salaries and benefits and the cost of
materials such as masks, wafers and evaluation parts. Research and development expenses were $12.0
million, or 13.9% of net revenues, during the first quarter of 2005, as compared to $11.5 million,
or 11.0% of net revenues, during the fourth quarter of 2004 and $11.8 million, or 11.3% of net
revenues, during the first quarter of 2004. Research and development expenses increased by 4.3% from
the fourth quarter of 2004 primarily due to an increase of $585 thousand in headcount related
expenses and $258 thousand in software licenses and support expenses offset by a decrease of
depreciation expenses of $352 thousand. Research and development expenses increased by 1.4% from the
first quarter of 2004 due primarily to an increase of $459 thousand in process qualification and
outside services expenses and $290 thousand in software licenses and support expenses offset by $438
thousand in headcount related expenses. We expect that research and development expenses will
increase in absolute dollars as we continue to develop new products and enhance existing products.
Sales and marketing. Sales and marketing expenses consist of commissions, headcount and
related costs, as well as travel, entertainment and promotional expenses. Sales and marketing
expenses were $7.3 million, or 8.5% of net revenues, in the first quarter of 2005, as compared to
$6.8 million, or 6.6% of net revenues, in the fourth quarter of 2004 and $6.9 million, or 6.6% of
net revenues, during the first quarter of 2004. Sales and marketing expenses increased 7.4% from the
fourth quarter of 2004 to the first quarter of 2005 primarily due to an increase of $412 thousand in
headcount related expenses. Sales and marketing expenses increased 5.9% from the first quarter of
2004 to the first quarter of 2005. The increase was primarily attributable to an increase of $513
thousand in headcount related expenses and $478 thousand in travel, samples freight and other
selling related expenses, offset by decreases of $412 thousand in commissions due to lower product
revenues and $233 thousand in logistic center fees as a result of decreased revenues through our
logistic center. Fluctuations in revenues will cause fluctuations in sales and marketing expenses as
it impacts our commission expenses. In future periods, we expect sales and marketing expenses will
increase in absolute dollars as we continue to expand our sales and marketing efforts.
General and administrative. General and administrative expenses consist of salaries and
related costs for administrative, executive and finance personnel, recruiting costs, professional
services and legal fees and allowances for doubtful accounts. General and administrative expenses
were $6.7 million, or 7.8% of net revenues, in the first quarter of 2005, as compared to $5.5
million, or 5.2% of net revenues, in the fourth quarter of 2004 and $4.0 million, or 3.8% of net22revenues, during the first quarter of 2004. Expenses increased from the fourth quarter of 2004 by
22.9% primarily due to an increase of $1.2 million in headcount related expenses, $961 thousand in
outside services, largely attributable to costs associated with compliance under Sarbanes-Oxley, and
$244 thousand in legal fees, offset by a reduction of bad debt expenses of $756 due to lower
receivables and a decrease of $352 thousand in depreciation expense. The increase in general and
administrative expenses of 67.6% from the first quarter of 2004 was primarily due to increased
outside services of $1.7 million mainly due to services related to compliance of Sarbanes-Oxley and
headcount related expenses of $981 thousand. We anticipate that general and administrative expenses
may increase in absolute dollars as we scale our facilities, infrastructure, and headcount to
support our overall expected growth. We may also incur additional expenses in connection with the
Atmel, shareholder class action and shareholder derivative litigation. For further information on
this litigation see "Legal Proceedings."
Other operating expenses. In the fourth quarter of 2004, there were other operating
expenses of $4.2 million. There wereno other operating expenses during the first quarter of
2005 and the first quarter of 2004. The $4.2 million of operating expenses in the fourth quarter of
2004 related to in-process research and development expenses from acquisitions, of which $3.9
million related to the acquisition of G-Plus in the fourth quarter of 2004 and $251 thousand related
to the Emosyn acquisition.
Interest and other income. Interest and other income was $327 thousand, or 0.4% of net
revenues, during the first quarter of 2005, as compared to $405 thousand, or 0.4% of net revenues,
during the fourth quarter of 2004 and $394 thousand, or 0.4% of net revenues, during the first
quarter of 2004. Interest income decreased both from the fourth and first quarters of 2004 to the
first quarter of 2005 due to a decrease in invested cash.
Interest and other expense. Interest and other expense was $147 thousand for the first
quarter of 2005 as compared to $96 thousand for the fourth quarter of 2004 and $54 thousand for the
first quarter of 2004. Interest expense relates to interest on our notes payable.

Provision for Income Taxes
We maintained a full valuation allowance on our net deferred tax assets as of March 31,
2005.  The valuation allowance was determined in accordance with the provisions of Statement of
Financial Accounting Standards No. 109, or SFAS No. 109, "Accounting for Income Taxes," which
requires an assessment of both positive and negative evidence when determining whether it is more
likely than not that deferred tax assets are recoverable; such assessment is required on a
jurisdiction by jurisdiction basis. Cumulative losses incurred in the U.S. in recent years
represented sufficient negative evidence under SFAS No. 109 and accordingly, a full valuation
allowance was recorded against U.S. deferred tax assets.  We intend to maintain a full valuation
allowance in the U.S. deferred tax assets until sufficient positive evidence exists to support
reversal of the valuation allowance.

Our tax provision for the first quarter of 2005 was $746 thousand, which consists primarily of
foreign withholding taxes and tentative minimum tax.

Segment Reporting
Our operations involve the design, development, manufacturing, marketing and technical
support of our nonvolatile memory technology and products. We offer low to medium density devices
that target a broad range of existing and emerging applications in the digital consumer, networking,
wireless communications and Internet computing markets. Our products are differentiated based upon
attributes such as density, voltage, access speed, package and predicted endurance. We also license
our technology for use in non-competing applications. Our reportable segments are: the Standard
Memory Product Group, or SMPG, the Application Specific Product Group, or ASPG, the Special Product
Group, or SPG, the Emosyn Products, or Emosyn, the SST Communications Corporation Products, or SCC,
and Technology Licensing. Refer to Note 10 of the Notes to the Unaudited Condensed Consolidated
Financial Statements for revenue and gross profit information by reportable segment. Our analysis of
the changes for each segment is discussed below.

SMPG includes our standard flash memory product families: the MPF family and the MPF+ family.
SMPG revenues were $44.1 million for the first quarter of 2005, as compared to $51.6 million in the23fourth quarter of 2004 and $64.3 million in the first quarter of 2004. The decrease in revenues,
both from the fourth and first quarters of 2004, was primarily due to decreases in average selling
prices by 9.0% and 22.3%, respectively, and a 6.8% and 10.6% decrease in unit shipments from the
fourth and first quarters of 2004, respectively. Gross margin increased from negative 27.4% in the
fourth quarter of 2004 to negative 7.0% in the first quarter of 2005 primarily due to a provision
for inventory and adverse commitments of $23.2 million in the fourth quarter of 2004 compared to
$9.7 million in the first quarter of 2005. Gross margin decreased from 26.0% in the first quarter of
2004 to negative 7.0% in the first quarter of 2005 primarily due to a 22.3% decrease in average
selling prices of our products and a $9.5 million increase in provisions for inventory and adverse
purchase commitments related to lower of cost or market and excess inventory adjustments.

ASPG includes Concurrent SuperFlash, Serial Flash, Firmware Hub, or FWH, and Low Pin Count, or
LPC, flash products. ASPG also includes flash embedded controllers such as the ATA controller. ASPG
revenues were $19.8 million for the first quarter of 2005, as compared to $19.2 million in the
fourth quarter of 2004 and $18.1 million in the first quarter of 2004. While unit shipments
increased 21.5% from the fourth quarter of 2004, revenues remained fairly flat with an increase of
3.4% due to a 13.1% decrease in average selling prices. The increase in revenues from the first
quarter of 2004 was primarily due to a 29.5% increase in unit shipments, offset by a 14.8% decrease
in averge selling prices. Gross margin increased from 16.2% in the fourth quarter of 2004 to 31.6%
in the first quarter of 2005 primarily due to the benefit of previously reserved inventory and to
lower manufacturing costs achieved by transitioning manufacturing technology to lower geometries.
Gross margin increased from 29.9% in the first quarter of 2004 to 31.6% in the first quarter of 2005
primarily due to lower manufacturing costs achieved by transitioning manufacturing technology to
lower geometries and product mix, offset by a 14.8% decrease in average selling prices.

SPG includes ComboMemory, ROM/RAM Combos, SSF, MTP, FlashFlex51 microcontrollers and other
special flash products. SPG revenues were $6.7 million for the first quarter of 2005, as compared to
$11.8 million in the fourth quarter of 2004 and $9.0 million in the first quarter of 2004. The
decrease in revenues from the fourth quarter of 2004 was primarily due to a 32.4% decrease in unit
shipments combined with a 5.6% decrease in average selling prices. The decrease in revenues from the
first quarter of 2004 was primarily due to decreased unit shipments by 20.1% and a 9.4% decrease in
average selling prices. Gross margin decreased from 19.5% in the fourth quarter of 2004 and from
33.0% in the first quarter of 2004 to 6.1% in the first quarter of 2005. The decrease is primarily
due to a $1.7 million provision for inventory and adverse purchase commitments in the first quarter
of 2005, largely related to excess inventory, and a 9.4% and 5.6% decrease in average selling prices
from the first and fourth quarter of 2004, respectively.

Emosyn includes the Theseus Platinum product family and other
flash memory based microprocessor chips. We acquired a majority ownership of Emosyn on September 10,
2004.On April 15, 2005, we acquired the remaining minority interest of Emosyn
for $3.1 million in cash.Emosyn revenues were $7.9 million for the
first quarter of 2005, as compared to $13.5 million for the fourth quarter of 2004. The decrease in
revenue from the fourth quarter was a result of a 41.7% decrease in unit shipments and a 3.9%
decrease in average selling prices due to lower market demand. Gross margin increased from 15.1% in
the fourth quarter of 2004 to 26.9% in the first quarter of 2005 mainly due to favorable
manufacturing costs achieved through leveraging our existing processes.

SCC includes RF transceiver, synthesizer, power amplifier and switch
products. We formed SST Communications Corporation and acquired substantially all of the assets of
G-Plus, Inc. on November 5, 2004.SCC's revenues were $683 thousand
for the first quarter of 2005, as compared to $593 thousand for the fourth quarter of 2004. Gross
margin increased from negative 35.8% in the fourth quarter of 2004 to negative 26.2% in the first
quarter of 2005.

Revenue and gross profit related to technology licensing was $7.0 million in
the first quarter of 2005, as compared to $7.5 million in the fourth quarter of 2004 and $13.1
million in the first quarter of 2004. Revenues from license fees and royalties are recognized upon
the licensees' acceptance of the delivery of our engineering milestones. The decease in revenue in
the first quarter of 2005 to the first quarter of 2004 is due to higher license fees from new
licensees in the first quarter of 2004. Revenues from technology licensing fluctuate upon the timing
of the delivery of engineering milestones. We anticipate that revenues from technology licensing may
fluctuate significantly in the future.

PCT continues to earn commissions for point-of-sales to its customers. PCT's commissions are paid
at the same rate as all of our other stocking representatives in Asia. In addition, we continue to
pay SPT a fee for providing logistics center functions. This fee is based on a percentage of revenue
for each product shipped through SPT to our end customers. The fee paid to SPT covers the costs of
warehousing and insuring inventory and accounts receivable, the personnel costs required to maintain
logistics and information technology functions and the costs to perform billing and collection of
accounts receivable.

Liquidity and Capital Resources
Operating activities. Our operating activities used cash of $30.1 million for the
three months ended March 31, 2005 as compared to $3.6 million for the three months ended March 31,
2004. While we reported a net loss of $13.9 in the first quarter of 2005, this loss included
non-cash charges of $10.8 million for provision against inventory, $2.0 million of depreciation and
amortization and $895 thousand for provision of sales returns. Our primary usage of operating cash
flow in the first quarter of 2005 was the increase in inventory of $37.6 million. The increase in
inventory was concentrated in the early part of the first quarter for production that was started in
the fourth quarter of 2004. Also contributing to the increase in inventory was the lower shipment
volumes of our high density and smart card IC products. We reduced wafer starts during the first
quarter of 2005 and we expect our inventory levels will decrease in the second quarter of 2005. Cash
used in operating activities was also impacted by a $5.8 million decrease in trade accounts payable
and other accruals and liabilities. Cash used for inventory purchases and the payment of payables25and other liabilities was offset by an $11.6 million reduction in related and unrelated parties
accounts receivables and a decrease of $1.7 million in other assets. Accounts receivables decreased
due to a combination of cash collection and lower product revenue in the first quarter. We measure
the effectiveness of our collection efforts by an analysis of average days sales outstanding. Days
sales outstanding was 48 days in the first quarter of 2005 as compared to 59 days in the first
quarter of 2004. Collections of accounts receivable and related days sales outstanding will
fluctuate in future periods due to the timing and amount of our future revenues, customer payment
terms and the effectiveness of our collection efforts.
Investing activities. Our investing activities provided cash of $22.4 million for the
first quarter of 2005 as compared to a cash usage of $27.7 million for the first quarter of 2004.
Cash provided by investing activities in the first quarter of 2005 was primarily attributable to
$23.6 million of cash from the net sales and maturities of available-for-sale investments, offset by
$818 thousand in capital expenditures. In the first quarter of 2004, cash used in investing activity
related to our additional investments in Grace Semiconductor Manufacturing Corporation of $33.2
million and capital expenditures of $1.8 million, offset by net sales of available-for-sale
investments of $7.4 million.
Financing activities. Our financing activities provided cash of $2.5 million and $2.0
million during the first quarter of 2005 and 2004, respectively. Cash generated from financing
activities in the first quarter of 2005 primarily related to the issuance of common stock under the
employee stock purchase plan and the exercise of employee stock options totaling $1.6 million and
the borrowing against the line of credit of $1.0 million. In the first quarter of 2004, cash
generated from financing activities primarily related to issuance of common stock under the employee
stock purchase plan and the exercise of employee stock options totaling $2.1 million.
Principal sources of liquidity at March 31, 2005 consisted of $75.2 million of cash, cash
equivalents, and short-term available-for-sale investments.
As of March 31, 2005, other than as described below, there were no material changes in long-term
debt obligations, capital lease obligations, operating lease obligations, purchase obligations or
any other long-term liabilities reflected on our condensed consolidated balance sheet as compared to
December 31, 2004.
Purchase Commitments. As of March 31, 2005, we had outstanding purchase commitments with
our foundry vendors of $65.0 million for delivery in 2005. We have recorded a liability of $1.1
million for adverse purchase commitments. In comparison, as of December 31, 2004, we had outstanding
purchase commitments with our foundry vendors of $100.7 million for delivery in 2005, with a
recorded liability of $8.3 million for adverse purchase commitments.
Lease Commitments. We have long-term, non-cancelable building lease commitments. In 2001
and the second quarter of 2004, we recorded charges to other operating expense of $756 thousand and
$1.5 million, respectively, relating to operating leases for unoccupied buildings. These charges
represent the estimated difference between the total discounted future sublease income and our
discounted lease commitments relating to these buildings. At December 31, 2004 and March 31, 2005,
payments made have reduced the recorded liability to $976 thousand and $636 thousand, respectively.

Operating Capital Requirements. We believe that our cash balances, together with the funds
we expect to generate from operations, will be sufficient to meet our projected working capital and
other cash requirements through at least the next twelve months. However, there can be no assurance
that future events will not require us to seek additional borrowings or capital and, if so required,
that such borrowing or capital will be available on acceptable terms. Factors that could affect our
short-term and long-term cash used or generated from operations and as a result, our need to seek
additional borrowings or capital include:

the average selling prices of our products;
customer demand for our products;
the need to secure future wafer production capacity from our suppliers;
the timing of significant orders and of license and royalty revenue; and
unanticipated research and development expenses associated with new product
introductions.26Please also see "Business Risks - Our operating results fluctuate
significantly, and an unanticipated decline in revenues may disappoint securities analyst or
investors and result in a decline in our stock price."
On May 7, 2002, a judgment was entered against us regarding the infringement of two U.S. patents
in the amount of $36.5 million. We appealed the judgment on July 16, 2002. On September 12, 2003 the
Court of Appeals upheld the jury's verdict. On November 18, 2003 the Court of Appeals denied our
request for a rehearing and in December 2003 we paid Atmel $37.8 million to satisfy the judgment
including statutory interest accrued during the appeals for the patent '811 and 829'. The other
patent remaining in the case, the '903 patent, is scheduled for trial on August 1, 2005. In the
event of unfavorable outcome of the trial, we may have to make an additional payment. For more
information, please also see "Business Risks - If we are accused of infringing the intellectual
property rights of other parties we may become subject to time-consuming and costly litigation. If
we lose, we could suffer a significant impact on our business and be forced to pay damages."
In January and February 2005, multiple putative shareholder class action complaints were filed
against us and certain directors and officers in the United States District Court for the Northern
District of California. Following the filing of the putative class action lawsuits, multiple
shareholder derivative complaints were filed in California Superior Court for the County of Santa
Clara, purportedly on behalf of SST against certain directors and officers. In the event of
unfavorable outcome of the suits, we may be required to pay damages. For more information, please
also see "Business Risks - If we become engaged in securities class action suits and derivative
suits, we may become subject to consuming and costly litigation and divert management resources and
could impact our stock price."
From time to time, we are also involved in other legal actions arising in the ordinary course of
business. We have accrued certain costs associated with defending these matters. There can be no
assurance the Atmel complaint, the shareholder class action complaints, the shareholder derivative
complaints or other third party assertions will be resolved without costly litigation, in a manner
that is not adverse to our financial position, results of operations or cash flows or without
requiring royalty payments in the future which may adversely impact gross margins. No estimate can
be made of the possible loss or possible range of loss associated with the resolution of these
contingencies. As a result, no losses have been accrued in our financial statements as of March 31,
2005.
Recent Accounting Pronouncements
In December 2004, the FASB issued SFAS 123R (revised 2004), or SFAS
123R, "Share Based Payment." SFAS 123R is a revision of FASB 123 and supersedes APB No. 25.
SFAS 123R establishes standards for the accounting for transactions in which an entity exchanges its
equity instruments for good or services or incurs liabilities in exchange for goods or services that
are based on the fair value of the entity's equity instruments. SFAS 123R focuses primarily on
accounting for transactions in which an entity obtains employee services in share-based payment
transactions. SFAS 123R requires an entity to measure the cost of employee services received in
exchange for an award of equity instruments based on the grant-date fair value of the award over the
period during which an employee is required to provide service for the award. The grant-date fair
value of employee share options and similar instruments must be estimated using option-pricing
models adjusted for the unique characteristics of those instruments unless observable market prices
for the same or similar instruments are available. In addition, SFAS 123R requires a public entity
measure the cost of employee services received in exchange for an award of liability instruments
based on its current fair value and that the fair value of that award will be remeasured
subsequently at each reporting date through the settlement date. In April 2005, the U. S. Securities
and Exchange Commission adopted a new rule that amends the compliance dates of SFAS 123R. The
effective date of SFAS 123R for us is for the first interim period of 2006. Although we have not yet
determined whether the adoption of SFAS 123R will result in amounts that are similar to the current
pro forma disclosures under SFAS123, we are evaluating the requirements under SFAS 123R and expect
the adoption to have a significant adverse impact on our consolidated operating expenses.
In March 2005, the FASB issued FSP No. 46R-5, "Implicit Variable Interests under FASB
Interpretation No. 46 (revised December 2003), Consolidation of Variable Interest Entities", or
FSP46R-5, which provides guidance for a reporting enterprise on whether it holds an implicit
variable interest in a variable interest entity (VIE) or potential VIE when specific conditions
exist. FSP46R-5 is effective the first period beginning after March 3, 2005 and, accordingly, is27being adopted by us as of April 1, 2005. We are currently evaluating the effect that the adoption of
FSP46R-5 will have on our consolidated results of operations and financial condition but do not
expect it to have a material impact.

Business Risks
Risks Related to Our Business
Our operating results fluctuate materially, and an unanticipated decline in
revenues may disappoint securities analysts or investors and result in a decline in our stock
price.
Although we were profitable for the first three quarters of 2004, we incurred net losses for
2001, 2002, 2003 the fourth quarter of 2004 and the first quarter of 2005. Our operating results
have fluctuated significantly and our past financial performance should not be used to predict
future operating results. Our recent quarterly and annual operating results have fluctuated, and may
continue to fluctuate, due to the following factors, all of which are difficult to forecast and many
of which are out of our control:

the availability, timely delivery and cost of wafers or other manufacturing and assembly
services from our suppliers;
competitive pricing pressures and related changes in selling prices;
fluctuations in manufacturing yields and significant yield losses;
new product announcements and introductions of competing products by us or our competitors;
product obsolescence;
lower of cost or market, obsolescence or other inventory adjustments;
changes in demand for, or in the mix of, our products;
the gain or loss of significant customers;
market acceptance of products utilizing our SuperFlashâtechnology; 
changes in the channels through which our products are distributed and the timeliness of receipt
of distributor resale information;
exchange rate fluctuations;
general economic, political and environmental-related conditions, such as natural disasters;
increases in allowance for doubtful accounts;
valuation allowances on deferred tax assets based on changes in estimated future taxable income;
difficulties in forecasting, planning and management of inventory levels;
unanticipated research and development expenses associated with new product introductions; and
the timing of significant orders and of license and royalty revenue.

As recent experience confirms, a downturn in the market for products such as personal computers
and cellular telephones that incorporate our products can also harm our operating results.
Our operating expenses are relatively fixed, and we order materials in advance of anticipated
customer demand. Therefore, we have limited ability to reduce expenses quickly in response to any
revenue shortfalls.
Our operating expenses are relatively fixed, and we therefore have limited ability to reduce
expenses quickly in response to any revenue shortfalls. Consequently, our operating results will be
harmed if our revenues do not meet our projections. We may experience revenue shortfalls for the
following reasons:

sudden drops in consumer demand which may cause customers to cancel backlog, push out shipment
schedules, or reduce new orders, possibly due to a slowing economy or inventory corrections among
our customers;
significant declines in selling prices that occur because of competitive price pressure during
an over-supply market environment;28sudden shortages of raw materials for fabrication, test or assembly capacity constraints that
lead our suppliers to allocate available supplies or capacity to other customers which, in turn,
harm our ability to meet our sales obligations; and
the reduction, rescheduling or cancellation of customer orders.In addition, political or economic events beyond our control can suddenly result in increased
operating costs. For example, the terrorist attacks of September 11, 2001 have resulted in a
substantial increase to our business insurance costs. In addition, under a recently approved
standard, we will be required to record compensation expense on stock option grants, which may
substantially increase our operating costs and impact our earnings (loss) per share.
We incurred significant inventory valuation adjustments in 2003, 2004 and the
first quarter of 2005, and we may incur additional significant inventory valuation adjustments in
the future.
We typically plan our production and inventory levels based on internal forecasts of customer
demand, which are highly unpredictable and can fluctuate materially. The value of our inventory is
dependent on our estimate of future average selling prices, and, if our projected average selling
prices are over estimated, we may be required to adjust our inventory value to reflect the lower of
cost or market. As of March 31, 2005, we had $176.2 million of inventory on hand, an increase of
$19.6 million, or 12.5%, from December 31, 2004. Total valuation adjustments to inventory and
adverse purchase commitments were $6.7 million in 2003, $35.9 million in 2004 and $10.8 million in
the first quarter of 2005. Due to the large number of units in our inventory, even a small change in
average selling prices could result in a significant adjustment and could harm our financial
results. Some of our customers have requested that we ship them product that has a finished goods
date of manufacture that is less than one year old. As of March 31, 2005, our allowance for excess
and obsolete inventories includes an allowance for our on hand finished goods inventory with a date
of manufacture of greater than two years old and for certain products with a date of manufacture of
greater than one year old. In the event that this becomes a common requirement, it may be necessary
for us to provide for an additional allowance for our on hand finished goods inventory with a date
of manufacture of greater than one year old, which could result in a significant adjustment and
could harm our financial results.
Cancellations or rescheduling of backlog may result in lower future revenue and harm our
business.
Due to possible customer changes in delivery schedules and cancellations of orders, our
backlog at any particular date is not necessarily indicative of actual sales for any succeeding
period. A reduction of backlog during any particular period, or the failure of our backlog to result
in future revenue, could harm our business in the future. We experienced a sharp downturn in several
of our markets late in 2000 through 2002, as our customers reacted to weakening demand for their
products. We began to experience a slow recovery during 2002 through the first half of 2003. During
the second half of 2003 and the first quarter of 2004, demand for our products increased sharply and
we began to see improvements in the average selling prices of our products. However, during the
second half of 2004 and the first quarter of 2005, we experienced a demand slow-down for our
products. Our business could be harmed by industry-wide fluctuations in the future.
Our business may suffer due to risks associated with international sales and operations.
During 2003, 2004 and the three months ended March 31, 2005, our export product and licensing
revenues accounted for 92.9%, 92.7% and 93.4% of our net revenues, respectively. Our international
business activities are subject to a number of risks, each of which could impose unexpected costs on
us that would harm our operating results. These risks include:

difficulties in complying with regulatory requirements and standards;
tariffs and other trade barriers;
costs and risks of localizing products for foreign countries;
reliance on third parties to distribute our products;
extended accounts receivable payment cycles;
potentially adverse tax consequences;
limits on repatriation of earnings; and
burdens of complying with a wide variety of foreign laws.29In addition, we have made equity investments in companies with operations in China, Japan and
Taiwan. The value of our investments is subject to the economic and political conditions particular
to their industry, their countries and to foreign exchange rates and to the global economy. If we
determine that a change in the recorded value of an investment is other than temporary, we will
adjust the value of the investment. Such an expense could have a negative impact on our operating
results.
We derived 90.0%, 86.0% and 82.7% of our net product revenues from Asia during 2003, 2004 and the
three months ended March 31, 2005, respectively. Additionally, substantially all of our wafer
suppliers and packaging and testing subcontractors are located in Asia. Any kind of economic,
political or environmental instability in this region of the world can have a severe negative impact
on our operating results due to the large concentration of our production and sales activities in
this region. For example, during 1997 and 1998, several Asian countries where we do business, such
as Japan, Taiwan and Korea, experienced severe currency fluctuation and economic deflation, which
negatively impacted our revenues and also negatively impacted our ability to collect payments from
customers. During this period, the lack of capital in the financial sectors of these countries made
it difficult for our customers to open letters of credit or other financial instruments that are
guaranteed by foreign banks. Finally, the economic situation during this period exacerbated a
decline in selling prices for our products as our competitors reduced product prices to generate
needed cash.
It should also be noted that we are greatly impacted by the political, economic and military
conditions in Taiwan. Taiwan and China are continuously engaged in political disputes and both
countries have continued to conduct military exercises in or near the other's territorial waters and
airspace. Such disputes may continue and even escalate, resulting in an economic embargo, a
disruption in shipping or even military hostilities. Any of these events could delay production or
shipment of our products. Any kind of activity of this nature or even rumors of such activity could
harm our operations, revenues, operating results, and stock price.
Terrorist attacks and threats, and government responses thereto, could harm our business.
Terrorist attacks in the United States or abroad against American interests or citizens, U.S.
retaliation for these attacks, threats of additional terrorist activity and the war in Iraq have
caused our customer base to become more cautious. Any escalation in these events or similar future
events may disrupt our operations or those of our customers, distributors and suppliers, affect the
availability of materials needed to manufacture our products, or affect the means to transport those
materials to manufacturing facilities and finished products to customers. In addition, these events
have had and may continue to have an adverse impact on the U.S. and world economy in general and
consumer spending in particular, which could harm our business.
We do not typically enter into long-term contracts with our customers, and the loss of a major
customer could harm our business.
We do not typically enter into long-term contracts with our customers. In addition, we cannot
be certain as to future order levels from our customers. In the past, when we have entered into a
long-term contract, the contract has generally been terminable at the convenience of the customer.
We depend on stocking representatives and distributors to generate a majority of our revenues.
We rely on stocking representatives and distributors to establish and maintain customer
relationships and to sell our products. These stocking representatives and distributors could
discontinue their relationship with us or discontinue selling our products at any time. The majority
of our stocking representatives are located in Asia. The loss of our relationship with any stocking
representative or distributor could harm our operating results by impairing our ability to sell our
products to our end customers.

We depend on SPT, our logistics center, to support many of our customers in Asia.
Since 2001, we have been increasing our out-sourcing activities with our customer service
logistics to support our customers. Currently SPT supports our customers in Taiwan, China and other
Southeast Asia countries. SPT provides planning, warehousing, delivery, billing, collection and30other logistic functions for us in these regions. SPT is a wholly owned subsidiary of one of our
stocking representatives in Taiwan, PCT. During 2003, 2004 and the three months ended March 31,
2005, SPT serviced end customer shipments accounted for 64.2%, 52.9% and 51.3% of our net product
revenues recognized, respectively. As of December 31, 2004 and March 31, 2005, the accounts
receivable from SPT accounted for 55.1% and 47.6%, respectively, of our net accounts receivable. For
further description of our relationships with PCT and SPT, please refer to "Management's Discussion
and Analysis of Financial Condition and Results of Operation - Related Party Transactions" in our
Annual Report on Form 10-K for the year ended December 31, 2004.
We do not have any long-term contracts with SPT, PCT or SPAC, and SPT, PCT or SPAC may cease
providing services to us at any time. If SPT, PCT or SPAC were to terminate their relationship with
us we would experience a delay in reestablishing warehousing, logistics and distribution functions,
which could impair our ability to collect accounts receivable from SPT and may harm our
business.
We depend on a limited number of foreign foundries to manufacture our products, and these
foundries may not be able to satisfy our manufacturing requirements, which could cause our revenues
to decline.
We outsource substantially all of our manufacturing and testing activities. We currently buy
all of our wafers and sorted die from a limited number of suppliers. Substantially all of our
products are manufactured by six foundries, TSMC in Taiwan, Sanyo, Seiko-Epson and Yasu in Japan,
Grace in China and Samsung in Korea. We have invested $83.2 million in GSMC, a Cayman Islands
company, which owns a wafer foundry subsidiary, Grace, in Shanghai, China. We anticipate that these
foundries, together with Shanghai Hua Hong NEC Electronic Company Limited, or HHNEC and Vanguard in
Taiwan will manufacture substantially all of our products in 2005. If these suppliers fail to
satisfy our requirements on a timely basis at competitive prices we could suffer manufacturing
delays, a possible loss of revenues or higher than anticipated costs of revenues, any of which could
harm our operating results.
Our revenues may be impacted by our ability to obtain adequate wafer supplies from our foundries.
The foundries with which we currently have arrangements, together with any additional foundry at
which capacity might be obtained, may not be willing or able to satisfy all of our manufacturing
requirements on a timely basis at favorable prices. In addition, we have encountered delays in
qualifying new products and in ramping-up new product production and we could experience these
delays in the future. We are also subject to the risks of service disruptions, raw material
shortages and priceincreases by our foundries. Such disruptions, shortages and price
increases could harm our operating results.
Manufacturing capacity has in the past been difficult to secure and if capacity constraints
arise in the future our revenues may decline.
In order to grow, we need to increase our present manufacturing capacity. We currently
believe that the existing capacity plus additional future capacity from Grace, HHNEC and Vanguard
available to us will be sufficient through 2005. However, events that we have not foreseen could
arise which would limit our capacity. Similar to our aggregate $83.2 million investment in GSMC, we
may determine that it is necessary to invest substantial capital in order to secure appropriate
production capacity commitments. If we cannot secure additional manufacturing capacity on acceptable
terms, our ability to grow will be impaired and our operating results will be harmed.
Our cost of revenues may increase if we are required to purchase manufacturing capacity in
the future.
To obtain additional manufacturing capacity, we may be required to make deposits, equipment
purchases, loans, joint ventures, equity investments or technology licenses in or with wafer
fabrication companies. These transactions could involve a commitment of substantial amounts of our
capital and technology licenses in return for production capacity. We may be required to seek
additional debt or equity financing if we need substantial capital in order to secure this capacity
and we cannot assure you that we will be able to obtain such financing.

31If our foundries fail to achieve acceptable wafer manufacturing yields, we will experience higher
costs of revenues and reduced product availability.
The fabrication of our products requires wafers to be produced in a highly controlled and
ultra-clean environment. Semiconductor companies that supply our wafers have, from time to time,
experienced problems achieving acceptable wafer manufacturing yields. Semiconductor manufacturing
yields are a function of both our design technology and the foundry's manufacturing process
technology. Low yields may result from marginal design or manufacturing process drift. Yield
problems may not be identified until the wafers are well into the production process, which often
makes them difficult, time consuming and costly to correct. Furthermore, we rely on independent
foundries for our wafers which increases the effort and time required to identify, communicate and
resolve manufacturing yield problems. If our foundries fail to achieve acceptable manufacturing
yields, we will experience higher costs of revenues and reduced product availability, which could
harm our operating results.
If our foundries discontinue the manufacturing processes needed to meet our demands, or
failto upgrade the technologies needed to manufacture our products, we may face production
delays and lower revenues.
Our wafer and product requirements typically represent a small portion of the total
production of the foundries that manufacture our products. As a result, we are subject to the risk
that a foundry will cease production on an older or lower-volume manufacturing process that it uses
to produce our parts. Additionally, we cannot be certain our foundries will continue to devote
resources to advance the process technologies on which the manufacturing of our products is based.
Either one of these events could increase our costs and harm our ability to deliver our products on
time.
Our dependence on third-party subcontractors to assemble and test our products subjects us to
a number of risks, including an inadequate supply of products and higher costs of materials.
We depend on independent subcontractors to assemble and test our products. Our reliance on
these subcontractors involves the following significant risks:

reduced control over delivery schedules and quality;
the potential lack of adequate capacity during periods of strong demand;
difficulties selecting and integrating new subcontractors;
limited warranties on products supplied to us;
potential increases in prices due to capacity shortages and other factors; and
potential misappropriation of our intellectual property.These risks may lead to increased costs, delayed product delivery or loss of competitive
advantage, which would harm our profitability and customer relationships.
Because our flash memory products typically have lengthy sales cycles, we may experience
substantial delays between incurring expenses related to research and development and the generation
of revenues.
Due to the flash memory product cycle we usually require more than nine months to realize
volume shipments after we first contact a customer. We first work with customers to achieve a design
win,which may take three months or longer. Our customers then complete the design, testing
and evaluation process and begin to ramp up production, a period which typically lasts an additional
six months or longer. As a result, a significant period of time may elapse between our research and
development efforts and our realization of revenue, if any, from volume purchasing of our products
by our customers.
We face intense competition from companies with significantly greater financial, technical and
marketing resources that could harm sales of our products.
We compete with major domestic and international semiconductor companies, many of which have
substantially greater financial, technical, marketing, distribution, and other resources than we do.
Many of our competitors have their own facilities for the production of semiconductor memory32components and have recently added significant capacity for such production. Our low density memory
products, which presently account for substantially all of our revenues, compete against products
offered by Spansion (AMD/Fujitsu), Atmel, Intel, Macronix, STMicroelectronics, PMC and Winbond. Our
medium-density memory products compete with products offered by Spansion, Intel, STMicroelectronics,
Mitsubishi, Samsung, Sharp Electronics and Toshiba. If we are successful in developing our
high-density products, these products will compete principally with products offered by Spansion
(AMD/Fujitsu), Hynix, Intel, Renesas, Samsung, SanDisk, STMicroelectronics and Toshiba, as well as
any new entrants to the market.

In addition, we may in the future experience direct competition from our foundry partners. We
have licensed to our foundry partners the right to fabricate products based on our technology and
circuit design, and to sell such products worldwide, subject to our receipt of royalty payments.
Competition may also come from alternative technologies such as ferroelectric random access
memory devices, or FRAM, or other developing technologies.

Our markets are subject to rapid technological change and, therefore, our success depends on
our ability to develop and introduce new products.
The markets for our products are characterized by:

rapidly changing technologies;
evolving and competing industry standards;
changing customer needs;
frequent new product introductions and enhancements;
increased integration with other functions; and
rapid product obsolescence.To develop new products for our target markets, we must develop, gain access to and use leading
technologies in a cost-effective and timely manner and continue to expand our technical and design
expertise. In addition, we must have our products designed into our customers' future products and
maintain close working relationships with key customers in order to develop new products that meet
their changing needs.
In addition, products for communications applications are based on continually evolving industry
standards. Our ability to compete will depend on our ability to identify and ensure compliance with
these industry standards. As a result, we could be required to invest significant time and effort
and incur significant expense to redesign our products and ensure compliance with relevant
standards. We believe that products for these applications will encounter intense competition and be
highly price sensitive. While we are currently developing and introducing new products for these
applications, we cannot assure you that these products will reach the market on time, will
satisfactorily address customer needs, will be sold in high volume, or will be sold at profitable
margins.
We cannot assure you that we will be able to identify new product opportunities successfully,
develop and bring to market new products, achieve design wins or respond effectively to new
technological changes or product announcements by our competitors. In addition, we may not be
successful in developing or using new technologies or in developing new products or product
enhancements that achieve market acceptance. Our pursuit of necessary technological advances may
require substantial time and expense. Failure in any of these areas could harm our operating
results.
Our future success depends in part on the continued service of our key design engineering,
sales, marketing and executive personnel and our ability to identify, recruit and retain additional
personnel.
We are highly dependent on Bing Yeh, our President, Chief Executive Officer and Chairman of
our Board of Directors, as well as the other principal members of our management team and
engineering staff. There is intense competition for qualified personnel in the semiconductor
industry, in particular the highly skilled design, applications and test engineers involved in the
development of flash memory technology. Competition is especially intense in Silicon Valley, where33our corporate headquarters is located. We may not be able to continue to attract and retain
engineers or other qualified personnel necessary for the development of our business or to replace
engineers or other qualified personnel who may leave our employ in the future. Our anticipated
growth is expected to place increased demands on our resources and will likely require the addition
of new management and engineering personnel and the development of additional expertise by existing
management personnel. The failure to recruit and retain key design engineers or other technical and
management personnel could harm our business.
Our ability to compete successfully depends, in part, on our ability to protect our
intellectual property rights.
We rely on a combination of patent, trade secrets, copyrights, mask work rights,
nondisclosure agreements and other contractual provisions and technical measures to protect our
intellectual property rights. Policing unauthorized use of our products, however, is difficult,
especially in foreign countries. Litigation may continue to be necessary in the future to enforce
our intellectual property rights, to protect our trade secrets, to determine the validity and scope
of the proprietary rights of others, or to defend against claims of infringement or invalidity.
Litigation could result in substantial costs and diversion of resources and could harm our business,
operating results and financial condition regardless of the outcome of the litigation. We own 128
patents in the United States relating to our products and processes, with expiration dates ranging
from 2010 to 2023, and have filed for several more. In addition, we hold several patents in Europe
and Canada, and have filed several foreign patent applications in Europe, Japan, Korea, Taiwan and
Canada. We cannot assure you that any pending patent application will be granted. Our operating
results could be harmed by the failure to protect our intellectual property.
If we become engaged in securities class action suits and derivative suits, we may become
subject to consuming and costly litigation and divert management resources and could impact our
stock price.
Securities class action law suits are often brought against companies, particularly
technology companies, following periods of volatility in the market price of their securities.
Irrespective of the validity or the successful assertion of such claims, we could incur significant
costs and management resources in defending against such claims.
In January and February 2005, multiple putative shareholder class action complaints were filed
against us and certain directors and officers in the United States District Court for the Northern
District of California, following our announcement of anticipated financial results for the fourth
quarter of 2004. The complaints seek unspecified damages on alleged violations of federal securities
laws during the period from March 22, 2004 to December 20, 2004. Consolidation and the appointment
of a lead plaintiff are currently pending in these purported class actions.
In January and February 2005, following the filing of the putative class action lawsuits,
multiple shareholder derivative complaints were filed in California Superior Court for the County of
Santa Clara, purportedly on behalf of SST against certain directors and officers. The factual
allegations of these complaints are substantially identical to those contained in the putative
shareholder class actions filed in federal court. The derivative complaints assert claims for, among
other things, breach of fiduciary duty and violations of the California Corporations Code.
Public announcements may hurt our stock price. During the course of lawsuits there may be
public announcements of the results of hearings, motions, and other interim proceedings or
developments in the litigation. If securities analysts or investors perceive these results to be
negative, it could harm the market price of our stock.
Our litigation may be expensive, may be protracted and confidential information may be
compromised. We have incurred certain costs associated with defending these matters, and at any
time, additional claims may be filed against us, which could increase the risk, expense and duration
of the litigation. Further, because of the amount of discovery required in connection with this type
of litigation, there is a risk that some of our confidential information could be compromised by
disclosure. For more information with respect to our litigation, please also see "Part II, Item 1 - Legal Proceedings."

If we are accused of infringing the intellectual property rights of other parties we may
become subject to time-consuming and costly litigation. If we lose, we could suffer a significant
impact on our business and be forced to pay damages.
Third parties may assert that our products infringe their proprietary rights, or may assert
claims for indemnification resulting from infringement claims against us. Any such claims may cause34us to delay or cancel shipment of our products or pay damages that could harm our business,
financial condition and results of operations. In addition, irrespective of the validity or the
successful assertion of such claims, we could incur significant costs in defending against such
claims.
In the past we were sued both by Atmel Corporation and Intel Corporation regarding patent
infringement issues and sued Winbond Electronics Corporation regarding our contractual relationship
with them. Significant management time and financial resources have been devoted to defending these
lawsuits. We settled with Intel in May 1999, with Winbond in October 2000, and the Atmel litigation
is ongoing.
In addition to the Atmel, Intel and Winbond actions, we receive from time to time, letters or
communications from other companies stating that such companies have patent rights that involve our
products. Since the design of all of our products is based on SuperFlash technology, any legal
finding that the use of our SuperFlash technology infringes the patent of another company would have
a significantly negative effect on our entire product line and operating results. Furthermore, if
such a finding were made, there can be no assurance that we could license the other company's
technology on commercially reasonable terms or that we could successfully operate without such
technology. Moreover, if we are found to infringe, we could be required to pay damages to the owner
of the protected technology and could be prohibited from making, using, selling, or importing into
the United States any products that infringe the protected technology. In addition, the management
attention consumed by and legal cost associated with any litigation could harm our operating
results.
Public announcements may hurt our stock price. During the course of lawsuits there may be
public announcements of the results of hearings, motions, and other interim proceedings or
developments in the litigation. If securities analysts or investors perceive these results to be
negative, it could harm the market price of our stock.
Our litigation may be expensive, may be protracted and confidential information may be
compromised. On April 8, 2002, a jury found that we willfully infringed Atmel's '811 and '829
patents, and awarded Atmel $20.0 million in actual damages. On May 7, 2002, the court entered
judgment in the total amount of $36.5 million, which includes the original $20.0 million. The '811
and '829 patents expired in February 2002. Therefore, we are not precluded from selling any of our
products. On December 12, 2003, we paid Atmel $37.8 million to satisfy the judgement plus statutory
interest accrued during the appeal. The '903 patent case still remains open. The court found that we
infringed the '903 patent but the jury was unable to unanimously decide whether the '903 is valid
and a mistrial was declared. A settlement conference was originally scheduled for April 14, 2004 was
rescheduled for September 7, 2004. No conclusion was reached during the settlement conference on
September 7, 2004. A new trial date on the invalidity of the '903 patent has been scheduled for
August 1, 2005. If we are not successful in reaching a settlement, litigation may continue to
consume substantial amounts of our financial and managerial resources. We have incurred certain
costs associated with defending this matter, and at any time Atmel may file additional claims
against us, which could increase the risk, expense and duration of the litigation. Further, because
of the substantial amount of discovery required in connection with this type of litigation, there is
a risk that some of our confidential information could be compromised by disclosure. For more
information with respect to our litigation, please also see "Part II, Item 1 - Legal Proceedings."
If an earthquake or other natural disaster strikes our manufacturing facility or those of our
suppliers, we would be unable to manufacture our products for a substantial amount of time and we
would experience lost revenues.
Our corporate headquarters are located in California near major earthquake faults. In
addition, some of our suppliers are located near fault lines. In the event of a major earthquake or
other natural disaster near our headquarters, our operations could be harmed. Similarly, a major
earthquake or other natural disaster such as typhoon near one or more of our major suppliers, like
the earthquakes in September 1999 and March 2002 or the typhoon in September 2001 that occurred in
Taiwan, could potentially disrupt the operations of those suppliers, which could then limit the
supply of our products and harm our business.

35A virus or viral outbreak in Asia could harm our business.
We derive substantially all of our revenues from Asia and our logistics center is located in
Taiwan. A virus or viral outbreak in Asia, such as the SARS outbreak in early 2003, could harm the
operations of our suppliers, distributors, logistics center and those of our end customer, which
could harm our business.
Prolonged electrical power outages, energy shortages, or increased costs of energy could harm
our business.
Our design and process research and development facilities and our corporate offices are
located in California, which is susceptible to power outages and shortages as well as increased
energy costs. To limit this exposure, all corporate computer systems at our main California
facilities are on battery back-up. In addition, all of our engineering and back-up servers
and selected corporate servers are on generator back-up. While the majority of our
production facilities are not located in California, more extensive power shortages in the state
could delay our design and process research and development as well as increase our operating costs.
Our growth has in the past placed a significant strain on our management systems and resources
and if we fail to manage our growth, our ability to market or sell our products or develop new
products may be harmed.
Our business has in the past experienced rapid growth which strained our internal systems and
future growth will require us to continuously develop sophisticated information management systems
in order to manage our business effectively. We recently implemented a supply-chain management
system and a vendor electronic data interface system. There is no guarantee that these measures, in
themselves, will be adequate to address any growth, or that we will be able to foresee in a timely
manner other infrastructure needs before they arise. Our success depends on the ability of our
executive officers to effectively manage our growth. If we are unable to manage our growth
effectively, our results of operations will be harmed. If we fail to successfully implement new
management information systems, our business may suffer severe inefficiencies that may harm the
results of our operations.
Future changes in financial accounting standards or practices or existing taxation rules or
practices may cause adverse unexpected revenue fluctuations and affect our reported results of
operations.
A change in accounting standards or practices or a change in existing taxation rules or
practices can have a significant effect on our reported results and may even affect our reporting of
transactions completed before the change is effective. New accounting pronouncements and taxation
rules and varying interpretations of accounting pronouncements and taxation practice have occurred
and may occur in the future. Changes to existing rules or the questioning of current practices may
adversely affect our reported financial results or the way we conduct our business.
For example, changes requiring that we record compensation expense in the statement of operations
for stock options using the fair value method or changes in existing taxation rules related to stock
options could have a significant negative effect on our reported results. The FASB has issued
changes to generally accepted accounting principles in the United States that, when implemented in
the first quarter of 2006, will require us to record charges to earnings for the stock options we
grant.

Evolving regulation of corporate governance and public
disclosure may result in additional expenses and continuing uncertainty
Changing laws, regulations and standard relating to corporate governance
and public disclosure, including the Sarbanes-Oxley Act of 2002, new SEC regulations and Nasdaq
National Market rules are creating uncertainty for public companies. We continually evaluate and
monitor developments with respect to new and proposed rules and cannot predict or estimate the
amount of the additional costs we may incur or the timing of such costs. These new or changed laws,
regulations and standards are subject to varying interpretations, in many cases due to their lack of
specificity, and as a result, their application in practice may evolve over time as new guidance is
provided by regulatory and governing bodies. This could result in continuing uncertainty regarding
compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance
practices. We are committed to maintaining high standards of corporate governance and public
disclosure. As a result, we have invested resources to comply with evolving laws, regulations and36standards, and this investment has resulted in increased general and administrative expenses and may
result in a diversion of management time and attention from revenue-generating activities to
compliance activities. If our efforts to comply with new or changed laws, regulations and standards
differ from the activities intended by regulatory or governing bodies due to ambiguities related to
practice, regulatory authorities may initiate legal proceedings against us and we may be harmed.
We, and our independent registered public accounting firm, have determined that we have a
material weakness in our internal control over financial reporting. As a result, current and
potential stockholders could lose confidence in our financial reporting, which would harm our
business and the trading price of our stock.
Under Section 404 of the Sarbanes-Oxley Act of 2002, we are required to evaluate and
determine the effectiveness of our internal controls over financial reporting. We have dedicated a
significant amount of time and resources to ensure compliance with this legislation for the year
ended December 31, 2004 and will continue to do so for future fiscal periods. We may encounter
problems or delays in completing the review and evaluation, the implementation of improvements and
the receipt of a positive attestation, or any attestation at all, by our independent registered
public accounting firm. Additionally, management's assessment of our internal control over financial
reporting may identify deficiencies that need to be addressed in our internal control over financial
reporting or other matters that may raise concerns for investors.
As of December 31, 2004, we did not maintain effective control over accounting for and review of
the valuation of inventory, the income tax provision and related balance sheet accounts and
licensing revenue because we lacked a sufficient complement of personnel with a level of accounting
expertise that is commensurate with our financial reporting requirements. Specifically, we lacked
sufficient controls over the write down of inventory to the lower of cost or market, accounting for
complex licensing contracts with multiple elements, and processes and procedures related to the
determination and review of the quarterly and annual tax provisions in accordance with generally
accepted accounting principles in the United States. This control deficiency resulted in an audit
adjustment to the 2004 consolidated financial statements related to the write-down of inventory to
the lower of cost or market. Because of this material weakness, our management concluded that, as of
December 31, 2004, we did not maintain effective internal control over financial reporting based on
those criteria. As a result, PricewaterhouseCoopers LLP, issued an adverse opinion with respect to
our internal control over financial reporting and their report is included in our Annual Report on
Form 10-K for the year ended December 31, 2004. We have taken measures designed to address this
material weakness as further discussed in "Part I - Item 4. Controls and Procedures."

Should we, or our independent registered public accounting firm, determine in future fiscal
periods that we have additional material weaknesses in our internal control over financial
reporting, the reliability of our financial reports may be impacted, and our results of operations
or financial condition may be harmed and the price of our common stock may decline.

Acquisitions could result in operating difficulties, dilution and other harmful
consequences.
In September 2004 we acquired majority ownership in Emosyn, in November 2004 we acquired
substantially all of the assets of G-Plus and in April 2005, we entered into a Share Purchase
Agreement to acquire all of the outstanding capital stock of Actrans. We expect to continue to
evaluate and consider a wide array of potential strategic transactions, including business
combinations, acquisitions and dispositions of businesses, technologies, services, products and
other assets, including interests in our existing subsidiaries and joint ventures. At any given time
we may be engaged in discussions or negotiations with respect to one or more of such transactions.
Any of such transactions could be material to our financial condition and results of operations.
There is no assurance that any such discussions or negotiations will result in the consummation of
any transaction. The process of integrating any acquired business may create unforeseen operating
difficulties and expenditures and is itself risky. The areas where we may face difficulties include:diversion of management time, as well as a shift of focus from
operating the businesses to issues of integration and future products;


37declining employee morale and retention issues resulting from changes in compensation, reporting
relationships, future prospects, or the direction of the business;
the need to integrate each company's accounting, management information, human resource and
other administrative systems to permit effective management, and the lack of control if such
integration is delayed or not implemented;
the need to implement controls, procedures and policies appropriate for a public company at
companies that prior to acquisition had lacked such controls, procedures and policies; and in some
cases, the need to transition operations onto our platforms.International acquisitions involve additional risks, including those related to integration of
operations across different cultures and languages, currency risks, and the particular economic,
political, and regulatory risks associated with specific countries. Moreover, we may not realize the
anticipated benefits of any or all of our acquisitions. As a result of future acquisitions or
mergers, we might need to issue additional equity securities, spend our cash, or incur debt,
contingent liabilities, or amortization expenses related to intangible assets, any of which could
reduce our profitability and harm our business.

Risks Related to Our Industry
Our success is dependent on the growth and strength of the flash memory market.Substantially all of our products, as well as all new products currently under design, are
stand-alone flash memory devices or devices embedded with flash memory. A memory technology other
than SuperFlash may be adopted as an industry standard. Our competitors are generally in a better
financial and marketing position than we are from which to influence industry acceptance of a
particular memory technology. In particular, a primary source of competition may come from
alternative technologies such as FRAM devices if such technology is commercialized for higher
density applications. To the extent our competitors are able to promote a technology other than
SuperFlash as an industry standard, our business will be seriously harmed.
The selling prices for our products are extremely volatile and have historically declined
during periods of over capacity or industry downturns.
The semiconductor industry has historically been cyclical, characterized by periodic changes
in business conditions caused by product supply and demand imbalance. When the industry experiences
downturns, they often occur in connection with, or in anticipation of, maturing product cycles and
declines in general economic conditions. These downturns are characterized by weak product demand,
excessive inventory and accelerated decline of average selling prices. In some cases, downturns,
such as the one we experienced from late 2000 through 2002, have lasted for more than a year. Our
business could be further harmed by industry-wide prolonged downturns in the future. The flash
memory products portion of the semiconductor industry, from which we derive substantially all of our
revenues, suffered from excess capacity in 2001, 2002, 2003, in late 2004 and early 2005, which
resulted in greater than normal declines in our markets, which unfavorably impacted our revenues,
gross margins and profitability. While these conditions began to improve during the third quarter of
2003, deteriorating market conditions at the end of 2000 through the first part 2003 and again in
the fourth quarter of 2004 and the first quarter of 2005 have resulted in the decline of our selling
prices and harmed our operating results.
There is seasonality in our business and if we fail to continue to introduce new products this
seasonality may become more pronounced.
Sales of our products in the consumer electronics applications market are subject to
seasonality. As a result, sales of these products are impacted by seasonal purchasing patterns with
higher sales generally occurring in the second half of each year. In the past we have been able to
mitigate such seasonality with the introduction of new products throughout the year. If we fail to
continue to introduce new products, our business may suffer and the seasonality of a portion of our
sales may become more pronounced.

38Item 3. Quantitative and Qualitative Disclosures about Market Risk
We are exposed to risks associated with foreign exchange rate fluctuations due to our
international manufacturing and sales activities. These exposures may change over time as business
practices evolve and could negatively impact our operating results and financial condition.
Currently, we do not hedge these foreign exchange rate exposures. All of our sales are denominated
in U.S. dollars. An increase in the value of the U.S. dollar relative to foreign currencies could
make our products more expensive and therefore reduce the demand for our products. Such a decline in
the demand could reduce revenues and/or result in operating losses. In addition, a downturn in the
economies of China, Japan or Taiwan could impair the value of our equity investments in companies
with operations in these countries. If we consider the value of these companies to be impaired, we
will write down, or expense, some or all of our investments. In 2001, we wrote down our investment
in KYE by $3.3 million to $1.3 million due to an other than temporary decline in its market value.
At March 31, 2005, the recorded value of our KYE investment was $2.5 million based on the quoted
market price. In 2002, we wrote down our investment in Apacer, a privately held memory module
manufacturer located in Taiwan, by $7.8 million due to an other than temporary decline in its value.
As of March 31, 2005, the recorded value of our Apacer investment was $4.4 million. We have equity
investments in companies with operations in China, Japan, Taiwan and United States with recorded
values at March 31, 2005 of $86.8 million, $0.9 million, $16.6 million and $0.9 million,
respectively.

At any time, fluctuations in interest rates could affect interest earnings on our cash, cash
equivalents and available-for-sale investments, or the fair value of our investment portfolio. A 10%
move in interest rates as of March 31, 2005 would have an immaterial effect on our financial
position, results of operations, and cash flows. Currently, we do not hedge these interest rate
exposures. As of March 31, 2005, the carrying value of our available-for-sale investments
approximated fair value. The table below presents the carrying value and related weighted average
interest rates for our unrestricted and restricted cash, cash equivalents and available-for-sale
investments as of March 31, 2005 (in thousands):

                                                                             =========


Item 4. Controls and Procedures
Disclosure controls and procedures
We maintain disclosure controls and procedures that are designed to ensure that information
required to be disclosed in our reports filed or submitted pursuant to the Securities Exchange Act
of 1934, as amended, or the Exchange Act, is recorded, processed, summarized and reported within the
time periods specified in the Securities and Exchange Commission's rules and forms. Disclosure
controls and procedures also are designed to ensure that such information is accumulated and
communicated to our management, including our Chief Executive Officer and Chief Financial Officer,
as appropriate, to allow timely decisions regarding required disclosure. A control system, no matter
how well designed and operated, can provide only reasonable, not absolute, assurance that the
control system's objectives will be met.
A material weakness is a control deficiency, or combination of control deficiencies, that results
in more than a remote likelihood that a material misstatement of the annual or interim financial
statements will not be prevented or detected. As of December 31, 2004, our assessment of the
effectiveness of our internal control over financial reporting identified a material weakness in our
internal control over accounting for and review of the valuation of inventory, the income tax
provision and related balance sheet accounts and licensing revenue because we lacked a sufficient
complement of personnel with a level of accounting expertise that is commensurate with our financial
reporting requirements. Specifically, we lacked sufficient controls over the write down of inventory39to its lower of cost or market, accounting for complex licensing contracts with multiple elements,
and processes and procedures related to the determination and review of the quarterly and annual tax
provisions in accordance with generally accepted accounting principles in the United States. This
material weakness is discussed in greater detail in our Annual Report on Form 10-K for the year
ended December 31, 2004.
Our management, including the Chief Executive Officer and Chief Financial Officer, conducted an
evaluation of the effectiveness of our disclosure controls and procedures (as defined in Exchange
Act Rules 13a-15(e) and 15d-15(e)) as of March 31, 2005. Due to the material weakness discussed
above, our Chief Executive Officer and the Chief Financial Officer concluded that our disclosure
controls and procedures were not effective at the reasonable assurance level as of March 31,
2005.
Changes in internal control over financial reporting
During the first quarter of 2005, we implemented or began the implementation of the following
remediation steps to address the weakness discussed above:

We have hired new senior accounting personnel and are in the process of hiring additional
accounting and finance staff.
We have added a financial expert to the Audit Committee of our Board of Directors
We have commenced an enhanced training program for our accounting and finance personnel.
We have supplemented our internal accounting and finance personnel with third party experts
regarding selected accounting and tax matters.We expect to complete the implementation of these remedial measures during 2005 and believe that,
once fully implemented, these remedial measures will correct the material weakness discussed
above.
Except as discussed above, there have been no changes in our internal control over financial
reporting during the quarter ended March 31, 2005 that have materially affected or are reasonably
likely to materially affect our internal control over financial reporting, as defined in Rule
13a-15(f) under the Exchange Act.

40PART II - OTHER INFORMATION
Item 1. Legal Proceedings
In January 1996, Atmel Corporation filed suit against the SST alleging that we infringed six
U.S. patents. We successfully moved for summary judgment on two of the six asserted patents in
September 1997. In January 2001, Atmel withdrew its allegation that we infringed another patent. On
May 7, 2002, a judgment was entered against us in the amount of $36.5 million based on a jury's
fining that we infringed two of the three remaining patents. We appealed the judgment on July 16,
2002. On September 12, 2003 the Court of Appeals upheld the jury's verdict. On November 18, 2003 the
Court of Appeals denied our request for a rehearing, and in December 2003 we paid Atmel $37.8
million to satisfy the judgment plus statutory interest accrued during the appeals. The payment was
recorded as other operating expense in the year ending December 31, 2003. In addition, on June 28,
2004 we paid $247 thousand of legal related expenses incurred by Atmel pursuant to the court
order.
The third patent remaining in the case, the '903 patent, expired in September 2001. The trial
court has held that, if it is found to be valid, certain of our products infringed that patent. A
trial to determine whether the '903 patent is invalid began on July 29, 2002. On August 5, 2002 the
jury announced that it was unable to reach a verdict on our invalidity defense, and a mistrial was
declared. Atmel requested a new trial, but the Court stayed the matter until after our appeal of the
earlier judgment is resolved. At Atmel's request, the Court directed the parties to conduct a
settlement conference before a Magistrate Judge. That settlement conference was scheduled for April
14, 2004 and was subsequently rescheduled for September 7, 2004. No conclusion was reached during
the settlement conference on September 7, 2004. A new trial on the invalidity of the '903 patent has
been scheduled for August 1, 2005. The impact related to the outcome of the remaining patent is
undeterminable at this time.
In January and February 2005, multiple putative shareholder class action complaints were filed
against SST and certain directors and officers, in the United States District Court for the Northern
District of California, following our announcement of anticipated financial results for the fourth
quarter of 2004. The complaints are captioned: Hunt v. Silicon Storage Technology, Inc., et
al., Case No. C 05 00408 WHA (N.D. Cal.); Baker v. Silicon Storage Technology, Inc., et
al., Case No. C 05 00295 PJH (N.D. Cal.); Grobler v. Silicon Storage Technology, Inc., et
al., Case No. C 05 00376 MHP (N.D. Cal.); Talmo v. Silicon Storage Technology, Inc., et
al., Case No. C 05 00390 MMC (N.D. Cal.); and DiCintio v. Silicon Storage Technology, Inc.,
et al., Case No. C 05 0708 MMC (N.D. Cal.). The complaints seek unspecified damages on alleged
violations of federal securities laws during the period from March 22, 2004 to December 20, 2004.
Consolidation and the appointment of lead plaintiff are currently pending in these purported class
actions. We intend to take all appropriate action in response to these lawsuits. The impact related
to the outcome of these matters is undeterminable at this time.
In January and February 2005, following the filing of the putative class actions, multiple
shareholder derivative complaints were filed in California Superior Court for the County of Santa
Clara, purportedly on behalf of SST against certain directors and officers. The factual allegations
of these complaints are substantially identical to those contained in the putative shareholder class
actions filed in federal court. The derivative complaints assert claims for, among other things,
breach of fiduciary duty and violations of the California Corporations Code. These derivative
actions have been consolidated under the caption In Re Silicon Storage Technology, Inc.
Derivative Litigation, Lead Case No. 1:05CV034387 (Cal. Super. Ct., Santa Clara Co.). We intend
to take all appropriate action in response to these lawsuits. The impact related to the outcome of
these matters is undeterminable at this time.
From time to time, we are also involved in other legal actions arising in the ordinary course of
business. We have incurred certain costs while defending these matters. There can be no assurance
the remaining Atmel complaint, the shareholder class action complaints, the shareholder derivative
complaints or other third party assertions will be resolved without costly litigation, in a manner
that is not adverse to our financial position, results of operations or cash flows or without
requiring royalty payments in the future which may adversely impact gross margins. No estimate can
be made of the possible loss or possible range of loss associated with the resolution of these
contingencies. As a result, no losses have been accrued in our financial statements as of March 31,
2004.
