                                     PART I

ITEM 1. BUSINESS

GENERAL

     Integrated Silicon Solution, Inc. designs, develops and markets high
performance memory semiconductors used in Internet access devices, networking
equipment, telecom and mobile communications equipment, and computer
peripherals. Our high speed and low power SRAMs and our low to medium density
DRAMs enable customers to design products that meet the demanding connectivity
and portability requirements of the data communications and wireless
communications markets. Our objective is to capitalize on major trends such as
the expansion of the communications and Internet infrastructure, the
proliferation of wireless devices, and other trends in electronics technologies.

     The ever-expanding performance requirements in electronic systems place
increasing pressure on manufacturers to use sophisticated semiconductor memory
architecture within their systems. Manufacturers of leading-edge internet access
devices, ISP servers and networking routers and switches require high speed
memory architecture and devices within their systems to meet demands for faster
speed and response times. Similarly, the advent of handheld wireless
communications devices, such as cellular phones and personal digital assistants,
has necessitated the development of high performance memories that reduce power
consumption, increase battery life, and reduce size in order to maximize
portability. Our goal is to be a focused supplier of high performance memories
targeting the growing connectivity and communications markets.

     Our customers include industry leaders such as 3Com, Alcatel, Cisco,
Ericsson, Hewlett Packard, IBM, Lexmark, Motorola, Nokia and Seagate. Due to
their size and influence, these customers generally drive memory volumes in
their market segment and help define the direction of future memory products.
Our products offer our customers numerous benefits, including:

     -    high performance and functionality;

     -    high quality and reliability;

     -    leading-edge designs that facilitate the development of new, advanced
          systems; and

     -    access to advanced process technology.

     We believe our close relationship with leading silicon wafer foundries
gives us access to the advanced wafer process technology required to design and
manufacture high performance memories. We entered into our first development
program with Taiwan Semiconductor Manufacturing Corporation ("TSMC") in 1990 and
with Chartered Semiconductor in 1994 and have also worked closely with United
Microelectronics Corporation ("UMC") since 1995. Through this collaborative
strategy, we have been in the forefront in utilizing the most advanced process
technology for memories and in securing access to wafer capacity.


                                       1


<PAGE>   4
     We believe our ability to design and develop high performance,
cost-effective products, and our collaborative development with our
manufacturing partners utilizing state-of-the-art process technology gives us a
competitive advantage. Our strategy is to:

     -    target high growth markets and applications;

     -    further penetrate industry leading customers;

     -    build collaborative relationships with leading edge foundries; and

     -    continually develop high performance products.

BACKGROUND

     ISSI was incorporated in California in October 1988 and changed our state
of incorporation to Delaware in August 1993. Our principal executive offices are
located at 2231 Lawson Lane, Santa Clara, California 95054, and our telephone
number is (408) 588-0800.

     We own approximately 39% of a privately-held company in Taiwan (Integrated
Circuit Solution, Inc. "ICSI", formerly known as ISSI-Taiwan) which focuses on
manufacturing coordination, quality assurance, product test, and regional sales
in the Asian market. Prior to the quarter ended March 31, 1999, our ownership of
ICSI exceeded 50% and our financial results were consolidated with those of
ICSI. Effective with the quarter ending March 31, 1999, we accounted for ICSI on
the equity basis and included in our financial statements our percentage share
of ICSI's financial results. In October 1998, we transferred our Flash memory
business to a newly formed company, NexFlash Technologies, Inc. ("NexFlash"),
and presently own approximately 32% of that company. In fiscal 1999, we
accounted for NexFlash on the equity basis and included in our financial
statements our percentage share of NexFlash's financial results. We also have a
wholly owned subsidiary in Hong Kong that primarily focuses on research and
development and a subsidiary in China that focuses on marketing.



PRODUCTS

     We are a focused supplier of a family of both high speed and ultra low
power SRAMs, complementary low and medium density DRAMs, and other complementary
memory products. In fiscal year 2000, we derived approximately 75% of our
revenue from SRAMs, 20% from DRAMs, and 5% from other products.

SRAMs

     Our high performance SRAM products generally focus on either very high
speed or very low power. Our first high speed SRAMs were shipped in 1990. More
recently, driven by increasing demand in the hand-held and mobile markets, such
as cellular phones, we have developed a low power family of products, including
a 1.8 volt low power SRAM for the next generation hand-held products. To date we
have derived substantially all of our SRAM revenues from the sale of high speed
SRAM products.

     We offer both asynchronous and synchronous high speed SRAMs Our high speed
asynchronous SRAMs are used in applications such as LANs, telecommunication
equipment, bridges, routers, modems, multimedia products, and industrial
instrumentation. Current asynchronous SRAM densities include 64K (8K x 8), 256K
(32K x 8), 512K (64K x 8 and 32K x 16), 1 megabit (128K x 8, 64K x 16), 2
megabit (128K x 16), 3 megabit (128K x 24), and 4 megabit (256K x 16 and 512K x
8). Our high speed synchronous SRAMs are used in a variety of networking and
telecommunications applications. Current synchronous densities include 1 Megabit
(32K x 32), 2 Megabit (64K x 32/36), 4 Megabit (256K x 16/18 and 128K x 32/36),
and 8 Megabit (256K x 32/36 and 512K x 18). Additional SRAM products are under
development and are expected to include performance-leading features in speed,
configuration, power levels, density, and packaging.

DRAMs

     Our low and medium density DRAM products complement our high performance
SRAM products. Applications for our DRAMs include telecommunications base
stations, set top boxes, networking equipment, disk drives, tape drives, and
printers. We currently offer 4, 8, and 16 megabit Fast Page Mode ("FPM"),
Extended Data


                                       2


<PAGE>   5
Out ("EDO"), plus 4 and 16 megabit SDRAM devices. Additional DRAM products are
under development. Our DRAM products are not targeted at the main memory DRAM
market.

OTHER MEMORY PRODUCTS

     Our other memory products include high performance serial EEPROMs, certain
microcontrollers, and voice recording chips. Applications for these products
include pagers, networking systems, modems, telephone sets, security systems,
smart cards, video games, and other consumer products.

DESIGN AND PROCESS TECHNOLOGY

     In the semiconductor industry, wafer fabrication facilities often use
memories in the development of advanced process technology because memory
products are particularly well suited for process research and development. Our
process development partnerships with TSMC and Chartered Semiconductor enable us
to design memories at leading edge geometries. Currently, we are designing new
products utilizing 0.18 micron, 0.15 micron, and 0.13 micron geometries. Our
technology development engineers work closely with our manufacturing partners in
this effort. The result is that we continue to produce SRAM products at the
leading edge of worldwide semiconductor capabilities and we believe that our
partnership development strategy gives us a competitive strength.

     Our design efforts focus on product specification, memory cell and array
structure, circuit design, simulation, and layout. We invest in advanced
computer aided design ("CAD") systems to ensure that the design team has
state-of-the-art design tools and employs innovative and rigorous design
methodologies. We utilize focused design teams for new product development and
can efficiently migrate proprietary design features to new generation products.

MANUFACTURING

     We combine our process technology expertise, foundry partnership strategy,
and equity investment arrangements to form a hybrid of the fab and fabless
business models which we call Fab-Lite(TM). We do not own or operate our own
wafer foundry but, because memory products are particularly well suited for the
development of advanced process technology, we actively participate in
developing and refining the process technology used to manufacture many of our
products. We believe that this strategy enables us to achieve the early
introduction of advanced geometries for our high performance memory products,
which results in increased performance and lower manufacturing costs. To date,
our principal manufacturing relationships have been with TSMC in Taiwan and with
Chartered Semiconductor in Singapore.

     In 1996, ISSI entered into a business venture agreement with Altera Inc.,
Analog Devices Inc., and TSMC wherein TSMC, as the general partner, would
construct a wafer fabrication facility in the state of Washington. The
fabrication facility is an advanced process technology facility capable of 0.35,
0.30, 0.25 and 0.18 micron process technology. The joint venture, named
WaferTech LLC, began production in 1998. As of September 30, 2000, our
investment in the business venture was $23.5 million.

     In 2000, ISSI entered into a wafer fabrication facility investment
agreement with Semiconductor Manufacturing International Corporation ("SMIC"), a
foundry currently under construction in Shanghai, China. Under the terms of this
agreement, ISSI has committed to invest $30 million. ISSI has received certain
capacity commitments from SMIC. Further, ISSI has agreed to be a process
technology development partner with SMIC. As of September 30, 2000, ISSI had
invested $4.6 million in this foundry, and $14.3 million and $11.1 million are
expected to be invested in fiscal years 2001 and 2002, respectively.

     The manufacturing of our products is coordinated jointly between our Santa
Clara headquarters and ICSI, which is located in close proximity to TSMC and UMC
in the Hsinchu Science-Based Industrial Park, a government-sponsored technology
development zone in Taiwan. When the independent wafer foundry partners complete
processed wafers, they move next to wafer testing. The wafers are then sawed or
cut into individual memory chips and the chips are inserted into final packages
and tested. Our U.S. headquarters develops and debugs test programs and tests
procedures used for screening product. Both the Taiwan and U.S. facilities have
clean rooms that are equipped for the wafer probe segment of the testing
process. Third party subcontractors in Taiwan and Singapore perform packaging
and assembly operations. A comprehensive quality control program is in place. We
have adopted ISO 9000 as our quality management standard. Our U.S. facility has
received certification under ISO 9001 standards. ICSI has received certification
under ISO 9002 standards.


                                       3


<PAGE>   6
     Each of our wafer suppliers also fabricates for other integrated circuit
companies, including certain of our competitors. In addition, UMC subsidiaries
manufacture integrated circuits, including SRAMs, for their own account.
Although we have written commitments specifying wafer capacities from our
suppliers, if these suppliers experience manufacturing failures or yield
shortfalls, choose to prioritize capacity for other use or reduce or eliminate
deliveries to us, there can be no assurance that we could enforce fulfillment of
the delivery commitments. We believe our technology development partnerships
mitigate such risk.

     There can be no assurance that the foundries we use will not encounter
construction or production difficulties or that they will allocate sufficient
wafer capacity to satisfy our wafer requirements, especially in times of wafer
capacity shortages. Moreover, there can be no assurance that we would be able to
qualify additional manufacturing sources for existing or new products in a
timely manner or that such additional manufacturing sources would be able to
produce an adequate supply of wafers. If we were unable to obtain an adequate
supply of wafers from our current or any alternative sources in a timely manner,
our business and operating results would be materially and adversely affected.

     Although our policy is to work closely with our manufacturing sources,
there are certain risks associated with the use of independent foundries,
including the absence of a controlled source of supply, or delays in obtaining
adequate wafer supplies. In addition, the manufacture of integrated circuits is
a highly complex and technically demanding process. Production yields and device
reliability can be affected by a large number of factors. As is typical in the
semiconductor industry, our outside foundries have from time to time experienced
lower than anticipated manufacturing yields and device reliability problems,
particularly in connection with the introduction of new products and changes in
such foundry's processing steps. There can be no assurance that our foundries
will not experience lower than expected manufacturing yields or device
reliability problems in the future, which could materially and adversely affect
our business and operating results.

     We have certain minimum wafer purchasing commitments to our foundry
partners in exchange for wafer capacity commitments. Although we have rights to
re-schedule or assign capacity to another party, there can be no assurance that
such re-schedule or assignment would be successfully accomplished. Should we
fail to re-schedule or assign unneeded capacity, our business and operating
results could be adversely affected.

CUSTOMERS AND MARKETING

     We have focused our marketing efforts on three major market segments that
include Internet access devices, networking, and telecom/mobile communications.
We market our products through a direct sales force, independent sales
representatives, and distributors. We have four distributors in North America
and distributors in most of the countries of Western Europe. We continue to
expand our marketing and sales activity in Europe. We have sales offices in the
United States, Europe, Hong Kong, and the People's Republic of China and,
through ICSI, in Taiwan and Japan. Our customers include a broad range of
electronic system manufacturers such as Alcatel, Cisco Systems, 3Com,
Hewlett-Packard, IBM, Motorola, and Seagate. In fiscal 2000 no single customer
accounted for over 10% of net sales. However, shipments for Cisco directly, or
indirectly through subcontractors, accounted for approximately 13% of net
revenue. In fiscal 1999 and 1998, one customer, 3Com, accounted for
approximately 20% and 19% of our net sales, respectively.

     Our sales and marketing efforts focusing on North America, Europe, and
South America are directed from our Santa Clara headquarters. ICSI has a direct
sales and marketing organization based in Taipei, Taiwan, which focuses on the
Asian market. In fiscal 2000, approximately 54% of our net sales was
attributable to customers located in the United States, 23% was attributable to
customers located in Europe, and 23% was attributable to customers located in
Asia. In fiscal 1999, approximately 52% of our net sales were attributable to
customers located in the United States, 20% were attributable to customers
located in Europe, and 28% were attributable to customers located in Asia. These
percentages exclude net sales by ICSI occurring after December 31, 1998, the
last date on which we consolidated ICSI results. In fiscal 1998, approximately
43% of our net sales were attributable to customers located in the United
States, 18% were attributable to customers located in Europe, and 39% were
attributable to customers located in Asia. The percentages for fiscal 1998
include net sales by ICSI. In fiscal 2000, international sales comprised
approximately 46% of our net sales. In fiscal 1999, international sales
(including our export sales and sales by ICSI for the quarter ending December
31, 1998) comprised approximately 48% of our net


                                       4


<PAGE>   7
sales. In fiscal 1998, international sales (our export sales and sales by ICSI)
comprised approximately 57% and 55% of our net sales, respectively. See Note 13
of Notes to Consolidated Financial Statements.

     We are subject to the risks of conducting business internationally,
including economic conditions in Asia, particularly Taiwan, changes in trade
policy and regulatory requirements, duties, tariffs and other trade barriers and
restrictions, the burdens of complying with foreign laws and, possibly,
political instability. We anticipate that sales to international customers will
continue to represent a significant percentage of net sales. Substantially all
of our foundries and assembly and test operations are located in Asia. Although
we transact business predominately in U.S. dollars, we do have some transactions
in New Taiwan ("NT") dollars and in Hong Kong ("HK") dollars. Such transactions
expose us to the risk of exchange rate fluctuations. We monitor our exposure to
foreign currency fluctuations, and from time to time have taken action to hedge
against such exposure, but have not to date adopted any formal hedging strategy.
There can be no assurance that exchange rate fluctuations will not materially
and adversely affect our business and operating results in the future.

     Our sales are generally made pursuant to standard purchase orders, which
can be revised to reflect changes in the customer's requirements. Generally,
purchase orders and OEM agreements allow customers to reschedule delivery dates
and cancel purchase orders without significant penalties. For these reasons, we
believe that our backlog, while useful for scheduling production, is not
necessarily a reliable indicator of future revenues.

COMPETITION

     The semiconductor memory market is intensely competitive and has been
characterized by cyclical market conditions, an oversupply of product, price
erosion, rapid technological change, short product life cycles, and foreign and
domestic competition. Our ability to compete successfully in the high
performance memory market depends on factors both within and outside of our
control, including over or under wafer manufacturing capacity and the resultant
imbalances in supply and demand, product pricing, the rate at which OEM
customers incorporate our products into their systems, the success of the OEM's
products, access to advanced process technologies at competitive prices, product
functionality, performance, and reliability, successful and timely product
development, wafer supply, wafer costs, achievement of acceptable yields of
functional die, the gain or loss of significant customers, the performance of
our competitors and general economic conditions. We may not be able to compete
successfully in the future as to any of these factors. Our failure to compete
successfully in these or other areas could materially and adversely affect our
business and operating results.

     The SRAM market is generally a fragmented market and specific competitors
and competitive factors vary based on geographic regions and market segments. In
the SRAM market, we compete with several major domestic and international
semiconductor companies including Alliance Semiconductor, Cypress Semiconductor,
Integrated Device Technology ("IDT"), Mitsubishi, Motorola, Samsung, and
Winbond. We also compete with new and emerging companies such as Giga
Semiconductor. We also may face significant competition from other domestic and
foreign integrated circuit manufacturers, which have advanced technological
capabilities but have not previously participated in the SRAM market sector. We
may not be able to compete successfully against any of these competitors.

     In the low to medium density DRAM area, we compete with Alliance,
Mosel-Vitelic, Vanguard and Oki. Other main memory DRAM companies could address
this market in the future. There can be no assurance that we will be able to
compete successfully against any of these competitors. In the EEPROM market, our
primary competitors include Atmel and SGS-Thomson Microelectronics. We also
compete with many small to medium-sized companies in one or more segments of the
market.

     Certain of our competitors offer broader product lines and have greater
financial, technical, marketing, distribution and other resources than us. We
may not be able to compete successfully against any of these competitors.

     The process technology used by our manufacturing sources, including process
technology that we have developed with our foundries, can be used by such
manufacturers to produce products for other companies, including our
competitors. Although we believe that our participation in the development of
the processes provides us the advantage of early access to such processes, the
knowledge of the manufacturer may be used to benefit our competitors.

PRODUCT WARRANTY

     Consistent with semiconductor memory industry practice, we generally
provide a limited warranty that our semiconductor memory devices are in
compliance with specifications existing at the time of delivery. Liability for a
stated warranty period is usually limited to replacement of defective items or
return of amounts paid.

RESEARCH AND DEVELOPMENT

     Rapid technological change and continuing price competition require
research and development efforts on both new products and advanced processes
employing smaller geometries. Our research and development activities are
focused primarily on the development of advanced process technologies and new
memory circuit designs. We currently design most of our high performance memory
products and jointly develop advanced process technology with our manufacturing
partners from our headquarters in Santa Clara, California.

     New SRAM products in design include 1.8 volt ultra low power 4 meg and 8
meg SRAMs, in addition to high speed 8 meg and 16 meg synchronous devices. These
new synchronous SRAMs include the new industry-standard Sigma RAMs. We have
several 64 meg DRAM devices under design. We are developing our new SRAM and
DRAM products on industry leading 0.13, 0.15, and 0.18 micron process
technologies. In nonvolatile memory, our future products are expected to include
128K, 256K, and 512K density serial EEPROM devices. Our research and development
expenditures in fiscal 2000, 1999, and 1998 were $18.3 million, $18.8 million,
and $31.9 million, respectively.

PATENTS

     As of September 30, 2000, we held 62 U.S. patents. These patents expire
between 2010 and 2020. We have approximately 7 additional patent applications
pending and expect to continue to file patent applications where appropriate to
protect our proprietary technologies. Although patents are an important element
of our intellectual property, we believe that our continued success depends
primarily on factors such as the technological skills and innovation of our
personnel rather than on our patents. The process of seeking patent protection
can be expensive and time consuming. There can be no assurance that patents will
be issued from pending or future applications or that, if patents are issued,
they will not be challenged, invalidated or circumvented, or that rights granted
thereunder will provide meaningful protection or other commercial advantage to
us. Moreover, there can be no assurance that any patent rights will be upheld in
the future or that we will be able to preserve any of our other intellectual
property rights.

     In the semiconductor industry, it is not unusual for companies to receive
notices alleging infringement of patents or other intellectual property rights
of others. We have been, and from time-to-time expect to be, notified of claims
that we may be infringing patents, maskwork rights or copyrights owned by third
parties. For example, for a number of years we have been corresponding with a
large international semiconductor company regarding potential infringement of
certain of their patents by us and certain of our patents by them. Other
companies may pursue claims against us with respect to the alleged infringement
of patents, maskwork rights, copyrights or other intellectual property owned by
third parties. If it appears necessary or desirable, we may seek licenses under
patents that we are alleged to be infringing. Although patent holders commonly
offer such licenses, licenses may not be offered and the terms of any offered
licenses may not be acceptable to us.

     The failure to obtain a license under a key patent or intellectual property
right from a third party for technology used by us could cause us to incur
substantial liabilities and to suspend the manufacture of the products utilizing
the invention or to attempt to develop non-infringing products, any of which
could materially and adversely affect our business and operating results.
Furthermore, we may become involved in protracted litigation regarding the
alleged infringement by us of third party intellectual property rights or
litigation to assert and protect our patents or other intellectual property
rights. Any litigation relating to patent infringement or other intellectual
property matters could result in substantial cost and diversion of our resources
which could harm our business.

EMPLOYEES

     As of September 30, 2000, we had approximately 164 employees in the U.S.,
approximately 22 in Taiwan, approximately 20 in the People's Republic of China,
and approximately 16 in Hong Kong. ICSI and NexFlash employed approximately 381
and 44 people, respectively, as of September 30, 2000. Total employment,
including affiliates, is therefore approximately 647 people. Our future success
will largely be dependent on our ability to attract, retain and motivate highly
qualified technical and management personnel. The employment market for such
personnel is extremely competitive and there can be no assurance that we will
successfully staff all necessary positions. Our employees are not represented by
any collective bargaining agreements and we have never experienced a work
stoppage. We believe that our employee relations are good.

ITEM 2. PROPERTIES

     Our U.S. headquarters occupy a two story building, totaling approximately
93,400 square feet, in Santa Clara, California in which our executive offices,
marketing, technology, product development groups and some research and
development ("R&D") testing facilities are located. The lease on this building
expires in February 2007. We sublease to NexFlash approximately 9,000 square
feet on a month to month lease. Additionally, we sublease approximately 24,000
square feet to a third party. The sublease expires in March 2003.


ITEM 3. LEGAL PROCEEDINGS

     In April 1998, the U.S. Department of Commerce ("DOC") published an
antidumping duty order on imports of SRAMs from Taiwan, from where we currently
import a majority of our SRAMs. As a consequence of this antidumping duty order,
we are required to post a cash deposit on imports of Taiwan fabricated SRAM
wafers or devices at the ad valorem rate of 7.56%.

     On April 28, 2000, Micron Technology Inc. ("Micron") requested an
administrative review of our Taiwan fabricated SRAMs for the period from April
1, 1999 through March 31, 2000. For entries during this period, the cash
deposits could be returned to us or, alternatively, we could forfeit amounts
deposited and owe duties and interest in addition to the amounts deposited,
depending on results of the DOC administrative review. The final results of the
review are expected in the year 2001 and will establish a new deposit rate for
subsequent entries, which may be higher or lower than the current rate.

     We have retained legal counsel to defend our interests in the antidumping
proceedings. In addition, respondents (including ISSI) have challenged certain
aspects of the antidumping determination in federal court proceedings. On August
29, 2000, pursuant to an appeal by ISSI and other respondents, the U.S. Court of
International Trade affirmed the International Trade Commission ("ITC") decision
to reverse the ITC's earlier ruling supporting the imposition of antidumping
duties and rule instead in favor of respondents. This decision by the Court of
International Trade has been appealed by Micron to the Federal Circuit Court of
Appeals. If such appeal is not successful, the antidumping case will be
terminated, the order will be revoked, and we will be entitled to a full refund
of cash deposits. Pending resolution of the appeal, the DOC will continue to
administer the antidumping order.

     Duties calculated and assessed by the government could have a material
adverse affect on our gross margins and profits. Any reviews or proceedings
might not mitigate or eliminate antidumping duties.


ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     There were no matters submitted to a vote of security holders during the
fourth quarter of fiscal 2000.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

RESULTS OF OPERATIONS

     Our financial results for fiscal 2000 reflect accounting for ICSI and
NexFlash on the equity basis and include our percentage share of the results of
ICSI's and NexFlash's respective operations. At September 30, 2000 we owned
approximately 39% of ICSI. Prior to the quarter ended March 31, 1999, our
ownership of ICSI exceeded 50% and our financial results were consolidated with
those of ICSI. Effective with the quarter ending March 31, 1999, we accounted
for ICSI on the equity basis and included in our financial statements our
percentage share of ICSI's financial results. In October 1998, we transferred
our Flash memory business to NexFlash, and presently own approximately 32% of
that company. In fiscal 1999, we accounted for NexFlash on the equity basis and
included in our financial statements our percentage share of NexFlash's
financial results.


FISCAL YEAR ENDED SEPTEMBER 30, 2000 COMPARED TO FISCAL YEAR ENDED SEPTEMBER 30,
1999

Net Sales. Net sales consist principally of total product sales less estimated
sales returns. Net sales increased by 70% to $141.9 million in fiscal 2000 from
$83.3 million in fiscal 1999. Net sales increased by $68.6 million to $141.9
million in fiscal 2000 from $73.3 million in fiscal 1999, excluding the $9.7
million in sales from ICSI and the $0.3 million in sales from NexFlash in the
December 31, 1998 quarter. The increase in sales was principally due to an
increase in unit shipments of our 1024K, 256K, and 128K x 24 SRAM products, as
well as increased unit shipments of DRAM products, specifically our 4 and 16
megabit DRAM products. In addition, the average selling prices of our SRAM and
DRAM products generally increased in fiscal 2000 compared to fiscal 1999. We
anticipate that the average selling prices of our existing products will
generally decline over time, although the rate of decline may fluctuate for
certain products. Such declines may not be offset by higher volumes or by higher
prices on newer products. See "Certain Factors Which May Affect Our Business or
Future Operating Results: Our sales depend on SRAM products, and a decline in
average selling prices or reduced demand for these products could harm our
business" and "We may not be able to compensate for price decreases in our
products."


                                       10


<PAGE>   13
     In fiscal 2000 no single customer accounted for over 10% of net sales.
However, shipments for Cisco directly, or indirectly through subcontractors,
accounted for approximately 13% of net revenue. In fiscal 1999, one customer,
3Com, accounted for approximately 20% of net sales. As sales to these customers
are executed pursuant to purchase orders and no purchasing contract exists,
these customers can cease doing business with us at any time. Net sales include
licensing revenue of approximately $1.0 million and $1.9 million in fiscal 2000
and fiscal 1999, respectively. Net sales include sales of approximately $0.9
million and $1.4 million to ICSI in fiscal 2000 and fiscal 1999, respectively.
Additionally, net sales include sales of approximately $0.2 million and $1.5
million in sales to NexFlash in fiscal 2000 and fiscal 1999, respectively.

     Gross Profit. Cost of sales includes die cost from the wafers acquired from
foundries, subcontracted package, assembly costs and test costs, costs
associated with in-house product testing, quality assurance and import duties.
Gross profit increased 168% to $44.2 million in fiscal 2000 from $16.5 million
in fiscal 1999. As a percentage of net sales, gross profit increased to 31.1% in
fiscal 2000 from 19.8% in fiscal 1999. The increase in gross profit was
principally due to an increase in unit shipments of our 1024K, 256K, and 128K x
24 SRAM products, as well as increased unit shipments of DRAM products,
specifically our 4 and 16 megabit DRAM products. In addition, increases in the
average selling prices of our SRAM and DRAM products in fiscal 2000 compared to
fiscal 1999 more than offset any increases in product costs resulting in higher
gross margins. Our gross profit also benefited from $1.0 million and $1.9
million of licensing revenue for fiscal 2000 and fiscal 1999, respectively. We
believe that the average selling price of our products will generally decline
over time and, unless we are able to reduce our cost per unit to the extent
necessary to offset such declines, the decline in average selling prices will
result in a material decline in our gross margin. In addition, product unit
costs could increase if suppliers raise prices, which could result in a material
decline in our gross margin. Although we have product cost reduction programs in
place for certain products that involve efforts to reduce internal costs and
supplier costs, there can be no assurance that product costs will be reduced or
that such reductions will be sufficient to offset the expected declines in
average selling prices. We do not believe that such cost reduction efforts are
likely to have a material adverse impact on the quality of our products or the
level of service we provide.

     Research and Development. Research and development expenses decreased by 3%
to $18.3 million in fiscal 2000 from $18.8 million in fiscal 1999. As a
percentage of net sales, research and development expenses decreased to 12.9% in
fiscal 2000 from 22.5% in fiscal 1999. The decrease in absolute dollars was
primarily the result of a $1.0 million reduction attributable to the
deconsolidation of ICSI and $0.3 million attributable of the spin-off of
NexFlash, offset by an increase in payroll related expenses and increased
expenses related to the development of new products. Fiscal 1999 included a
charge of $0.9 million in the June 1999 quarter for the write-off of certain
acquired licensed products and technologies which have been replaced by our
internally developed products. We anticipate that our research and development
expenses will increase in absolute dollars in future periods, although such
expenses may fluctuate as a percentage of net sales. During fiscal 2000, our
developments efforts were focused on ultra low power 4 meg and 8 meg SRAMs, high
speed 8 meg and 16 meg synchronous SRAM devices and 64 meg DRAM devices.

     Selling, General and Administrative. Selling, general and administrative
expenses increased by 31% to $15.6 million in fiscal 2000 from $11.9 million in
fiscal 1999. As a percentage of net sales, selling, general and administrative
expenses decreased to 11.0% in fiscal 2000 from 14.3% in fiscal 1999. The
increase in absolute dollars was primarily the result of increased selling
commissions associated with higher revenues in fiscal 2000 compared to fiscal
1999 as well as payroll related expenses, offset by a $1.2 million reduction
attributable to the deconsolidation of ICSI and $0.1 million attributable to the
spin-off of NexFlash. We expect our selling, general and administrative expenses
may increase in future quarters, although such expenses may fluctuate as a
percentage of net sales.

     Interest and other income (expense), net. Interest and other income, net
increased by $2.6 million to $3.8 million in fiscal 2000 from $1.2 million in
fiscal 1999. The increase results primarily from an increase of $3.1 million in
interest income as a result of higher cash balances from our follow-on public
stock offering in February 2000, offset by a decrease of $1.3 million in other
income attributable to the deconsolidation of ICSI.

     Gain on sale of investment. The gain on sale of investment decreased to
$0.8 million in fiscal 2000 from $2.6 million in fiscal 1999. Fiscal 2000
includes a pre-tax gain of approximately $0.8 million in the June 2000 quarter
related to the sale of an additional 8% of our holdings in ICSI. Fiscal 1999
includes a gain of approximately $1.8 million in the June 1999 quarter related
to the sale of our investment in UICC to UMC, a pre-tax gain of $1.2 million
resulting from the sale of 20% of our holdings in ICSI in the December 1998
quarter, offset by the loss of


                                       11


<PAGE>   14
approximately $0.4 million in the March 1999 quarter related to the sale of
approximately 33% of our investment in WaferTech LLC.

     Provision (benefit) for Income Taxes. The provision for income taxes for
fiscal 2000 is comprised of taxes on foreign earnings, foreign withholding taxes
and alternative minimum taxes. The provision for income taxes for fiscal 1999 is
primarily based on foreign withholding taxes related to the sale of ICSI stock
and other foreign withholding taxes.

     Under Statement of Financial Accounting Standards No. 109 (FAS 109),
deferred tax assets and liabilities are determined based on differences between
financial reporting and tax bases of assets and liabilities and are measured
using the enacted tax rates and laws that will be in effect when the differences
are expected to reverse. Management has established a valuation allowance
covering the net deferred tax assets based on management's belief that the
realization of the deferred tax assets is not realizable on a more likely than
not basis.

     Equity in net income of affiliated companies. Equity in net income of
affiliated companies increased by $9.9 million to $10.8 million in fiscal 2000
from $0.9 million in fiscal 1999. This primarily reflects an increase in income
from our percentage share of ICSI's financial results in fiscal 2000 from fiscal
1999.

FISCAL YEAR ENDED SEPTEMBER 30, 1999 COMPARED TO FISCAL YEAR ENDED SEPTEMBER 30,
1998

     Net Sales. Net sales decreased by 36% to $83.3 million in fiscal 1999 from
$131.1 million in fiscal 1998. Approximately $32.9 million of the decrease is
attributable to the deconsolidation of ICSI. Excluding the effect of the
deconsolidation of ICSI, the decrease in sales was principally due to a decrease
in the average selling prices of our SRAM products, as well as a significant
decline in unit shipments of our 256K and 256K module SRAM products. In
addition, revenue from shipments of newer 8 megabit and 16 megabit DRAM products
more than offset the decline in revenue from 4 megabit DRAM products. Net sales
include approximately $1.9 million of licensing revenue in fiscal 1999.
Moreover, net sales included approximately $1.4 million in sales to ICSI and
approximately $1.5 million in sales to NexFlash in fiscal 1999. Effective
January 1, 1999, our financial results no longer consolidate the sales of ICSI.
Sales to one customer, 3Com, accounted for approximately 20% and 19% of total
net sales for fiscal 1999 and fiscal 1998, respectively.

     Gross Profit. Gross profit increased 280% to $16.5 million in fiscal 1999
from $4.3 million in fiscal 1998. As a percentage of net sales, gross profit
increased to 19.8% in fiscal 1999 from 3.3% in fiscal 1998. The Company's gross
profit for fiscal 1999 benefited from $1.9 million in licensing revenue. In
fiscal 1998, the Company recorded inventory write-downs of $23.0 million
predominately for lower of cost or market issues on certain of our products,
primarily SRAMs. Excluding the inventory write-downs of $23.0 million for fiscal
1998, the decrease in gross profit dollars was principally due to a decrease in
the average selling prices of our SRAM products, as well as a significant
decline in unit shipments of our 256K and 256K module SRAM products.
Additionally, shipments and average selling prices of our 4 megabit DRAM product
declined significantly in fiscal 1999 compared to fiscal 1998. Although product
unit costs were generally lower in fiscal 1999 compared to fiscal 1998, such
reductions did not offset the declines in average selling prices resulting in
lower gross margins.

     Research and Development. Research and development expenses decreased by
41% to $18.8 million in fiscal 1999 from $31.9 million in fiscal 1998. As a
percentage of net sales, research and development expenses decreased to 22.5% in
fiscal 1999 from 24.3% in fiscal 1998. The decreases in absolute dollars were
primarily the result of the transfer of our Flash development efforts to
NexFlash, as well as reduced payroll related expenses associated with headcount
reductions, and limitations on discretionary spending during fiscal 1999. In
addition, a $5.1 million reduction in research and development expenses is
attributable to the deconsolidation of ICSI. Fiscal 1999 includes a charge of
$0.9 million in the June 1999 quarter for the write-off of certain licensed
products and technologies which have been replaced by the our internally
developed products. During fiscal 1999, we concentrated our development efforts
on SRAM and DRAM. SRAM projects focused on the development of a family of
ultra-low power products based on our six transistor memory cell. DRAM projects
included the 16 megabit EDO DRAM.

     Selling, General and Administrative. Selling, general and administrative
expenses decreased by 35% to $11.9 million in fiscal 1999 from $18.4 million in
fiscal 1998. As a percentage of net sales, selling, general and administrative
expenses increased slightly to 14.3% in fiscal 1999, from 14.0% in fiscal 1998.
The decrease in absolute dollars was primarily the result of a $3.1 million
reduction attributable to the deconsolidation of ICSI.


                                       12


<PAGE>   15
Additional reductions were the result of decreased selling commissions
associated with lower revenues, decreased payroll resulting from the spin-off of
NexFlash and a reduction in discretionary spending in fiscal 1999.

     In-process Technology. In December 1997, we completed our acquisition of
Nexcom Technology, Inc. in exchange for the issuance of 772,693 shares of Common
Stock, $0.5 million in cash, and the assumption of $1.2 million of net
liabilities (total consideration of approximately $8.5 million). In addition, we
incurred approximately $400,000 in other costs related to this transaction. The
transaction was accounted for as a purchase and resulted in an in-process
technology charge of $7.1 million in our December 31, 1997 quarter.

     Gain on sale of investment. The gain on sale of investment decreased to
$2.7 million in fiscal 1999 from $10.5 million in fiscal 1998. Fiscal 1999
includes a gain of approximately $1.8 million in the June 1999 quarter related
to the sale of our investment in UICC to UMC, a pre-tax gain of $1.2 million
resulting from the sale of 20% of our holdings in ICSI in the December 1998
quarter, offset by the loss of approximately $0.4 million in the March 1999
quarter related to the sale of approximately 33% of our investment in WaferTech
LLC. In June 1998, we sold approximately 46% of ICSI to a group of private
investors. We recorded a pre-tax gain of approximately $10.5 million in the June
1998 quarter related to this transaction.

     Interest and other income (expense), Net. Other income (expense), net
increased by $4.7 million to $1.2 million in fiscal 1999 from $(3.5) million in
fiscal 1998. This was primarily due to exchange gains in fiscal 1999 of $0.6
million compared to exchange losses in fiscal 1998 of $3.2 million as well as
interest expense of $1.8 million in 1998 compared to $1.0 million in 1999.

     Provision (benefit) for Income Taxes. The income tax provision for fiscal
1999 is comprised primarily of foreign withholding taxes related to the sale of
ICSI stock. The income tax provision for fiscal 1998 is comprised mainly of
foreign withholding taxes related to the sale of ICSI stock and a reversal of
previously recorded federal deferred tax assets which management has determined
should be subject to a valuation allowance based on historical and future
earnings trends.

LIQUIDITY AND CAPITAL RESOURCES

     As of September 30, 2000, our principal sources of liquidity included cash,
cash equivalents and short-term investments of approximately $97.6 million.
During fiscal 2000, operating activities used cash of approximately $13.6
million. Cash used by operations was primarily due to increases in inventories
of $33.5 million and increases in accounts receivable of $12.9 million related
to higher sales levels. These increases were partially offset by net income of
$25.0 million adjusted for equity in net income of affiliated companies of $10.8
million, depreciation of $3.2 million, and other non-cash items of $(0.6)
million and increases in accounts payable of $13.9 million.

     In fiscal 2000, we used $60.5 million for investing activities compared to
$6.5 million generated by investing activities in fiscal 1999. The cash used for
investing activities primarily resulted from net purchases of available-for-sale
securities of $51.1 million. We used $3.5 million for the acquisition of
equipment and other fixed assets. We made an initial investment of $4.6 million
in SMIC, additional investments of $2.7 million in WaferTech and $1.4 million in
NexFlash, and other investments of $0.6 million. We generated $3.3 million from
the sale of additional shares of ICSI stock.

     In fiscal 2000, we made capital expenditures of approximately $3.5 million
for engineering tools and computer software. In addition, we acquired $0.6
million of test equipment under a capital lease. We expect to spend
approximately $10.0 million to purchase capital equipment during the next twelve
months, principally for the purchase of design and engineering tools, additional
test equipment and computer software and hardware.

     We generated $96.9 million from financing activities during fiscal 2000
compared to $3.8 million in fiscal 1999. The primary source of financing for
fiscal 2000 was net proceeds from our follow-on public stock offering in the
March 2000 quarter of $90.7 million and proceeds from the issuance of common
stock of $6.3 million from option exercises and sales under our employee stock
purchase plan.

     In June 1998, we sold approximately 46% of ICSI to a group of private
investors. In December 1998, we sold an additional 20% of our holdings in ICSI
to a group of private investors resulting in a pre-tax gain of $1.2 million.
Proceeds from the transaction, net of withholding and transaction taxes, totaled
$6.6 million (including cash of $4.3 million and notes receivable of $2.3
million). After completion of this transaction, we owned approximately 43% of


                                       13


<PAGE>   16
ICSI and accounted for ICSI on the equity basis. In the quarter ended June 30,
2000, we sold an additional 8% of our holdings in ICSI to a group of private
investors for $3.3 million resulting in a pre-tax gain of $0.8 million.

     In August 2000, we entered into a wafer fabrication facility investment
agreement with SMIC, a foundry currently under construction in Shanghai, China.
Under the terms of this agreement, we have committed to invest $30.0 million. We
have received certain capacity commitments from SMIC. As of September 30, 2000,
we had invested $4.6 million in this foundry, and $14.3 million and $11.1
million are expected to be invested in fiscal years 2001 and 2002, respectively.

     In June 1996, we entered into a business venture called WaferTech, LLC with
TSMC, Altera, Analog Devices, and private investors to build a wafer fabrication
facility in Camas, Washington. We agreed to invest $31.2 million for a 4% equity
interest in the venture and, as of September 30, 1998, all of this amount had
been paid. In January 1999, we sold approximately 33% of our investment in
WaferTech to TSMC for $10.0 million. We retain a 2.67% interest in WaferTech. In
October 1999, the major investors in WaferTech made an additional pro-rata
investment in WaferTech. Our pro-rata amount of $2.7 million was invested along
with the other partners. Our investment in WaferTech as of September 30, 2000
was $23.5 million. In November 2000, we agreed to sell our interest in WaferTech
to TSMC for approximately $40.0 million. The transaction is expected to close by
December 31, 2000. We have minimum purchase obligations to TSMC related to
WaferTech. We are obligated to purchase from WaferTech or TSMC a minimum of 2.3%
of WaferTech's installed capacity. Our obligations related to WaferTech
terminate upon the completion of the sale of our interest in WaferTech to TSMC.
In fiscal 1995, we agreed to certain minimum wafer purchase commitments with
TSMC in exchange for wafer capacity commitments through 2001. We also agreed to
make certain annual payments to TSMC, the remaining amount of which totals
approximately $4.8 million through 2001, for additional capacity above the
annual base capacity. Wafer purchases in any given year are first applied to the
base capacity and then to our $4.8 million obligation. As a result, the $4.8
million may be subject to forfeiture if we do not purchase the base capacity and
additional capacity for which we have contracted. We do not currently expect to
forfeit any amounts or incur any losses associated with these capacity
agreements. Although we have rights to re-schedule or assign capacity to another
party, there can be no assurance that such re-schedule or assignment would be
successfully accomplished. Should we fail to re-schedule or assign unneeded
capacity, our business and operating results could be adversely affected.

     In April 1998, the U.S. Department of Commerce ("DOC") published an
antidumping duty order on imports of SRAMs from Taiwan, from where we currently
import a majority of our SRAMs. As a consequence of this antidumping duty order,
we are required to post a cash deposit on imports of Taiwan fabricated SRAM
wafers or devices at the ad valorem rate of 7.56%.

     On April 28, 2000, Micron Technology Inc. ("Micron") requested an
administrative review of our Taiwan fabricated SRAMs for the period from April
1, 1999 through March 31, 2000. For entries during this period, the cash
deposits could be returned to us or, alternatively, we could forfeit amounts
deposited and owe duties and interest in addition to the amounts deposited,
depending on results of the DOC administrative review. The final results of the
review are expected in the year 2001 and will establish a new deposit rate for
subsequent entries, which may be higher or lower than the current rate.

     We have retained legal counsel to defend our interests in the antidumping
proceedings. In addition, respondents (including ISSI) have challenged certain
aspects of the antidumping determination in federal court proceedings. On August
29, 2000, pursuant to an appeal by ISSI and other respondents, the U.S. Court of
International Trade affirmed the International Trade Commission ("ITC") decision
to reverse the ITC's earlier ruling supporting the imposition of antidumping
duties and rule instead in favor of respondents. This decision by the Court of
International Trade has been appealed by Micron to the Federal Circuit Court of
Appeals. If such appeal is not successful, the antidumping case will be
terminated, the order will be revoked, and we will be entitled to a full refund
of cash deposits. Pending resolution of the appeal, the DOC will continue to
administer the antidumping order.

     Duties calculated and assessed by the government could have a material
adverse affect on our gross margins and profits. Any reviews or proceedings
might not mitigate or eliminate antidumping duties.

     We believe our existing funds and available financing will satisfy our
anticipated working capital and other cash requirements through at least the
next 12 months. We may from time to time take actions to further increase our
cash position through bank borrowings, sales of additional shares of ICSI, the
disposition of certain assets, equity


                                       14


<PAGE>   17
financing or debt financing. From time to time, we also evaluate potential
acquisitions and equity investments complementary to our memory expertise and
market strategy, including investments in wafer fabrication foundries. To the
extent we pursue such transactions, any such transactions could require us to
seek additional equity or debt financing to fund such activities. There can be
no assurance that any such additional financing could be obtained on terms
acceptable to us, if at all.


CERTAIN FACTORS WHICH MAY AFFECT OUR BUSINESS OR FUTURE OPERATING RESULTS

OUR OPERATING RESULTS ARE EXPECTED TO CONTINUE TO FLUCTUATE AND MAY NOT MEET
PUBLISHED ANALYST FORECASTS. THIS MAY CAUSE THE PRICE OF OUR COMMON STOCK TO
DECLINE.

     Our future quarterly and annual operating results are subject to
fluctuations due to a wide variety of factors, including:

     -    the cyclicality of the semiconductor industry;

     -    declines in average selling prices of our products;

     -    oversupply of memory products in the market;

     -    our failure to introduce new products and to implement technologies on
          a timely basis;

     -    market acceptance of ours and our customers' products;

     -    the failure to anticipate changing customer product requirements;

     -    fluctuations in manufacturing yields;

     -    failure to deliver products on a timely basis;

     -    disruption in the supply of wafers or assembly services;

     -    changes in product mix;

     -    the timing of significant orders;

     -    increased expenses associated with new product introductions or
          process changes;

     -    the ability of customers to make payments to us; and

     -    increases in antidumping duties.

WE HAVE A RECENT HISTORY OF LOSSES, AND THERE CAN BE NO ASSURANCE THAT WE WILL
BE ABLE TO SUSTAIN PROFITABILITY IN THE FUTURE.

     We incurred losses of $9.5 million and $50.6 million in fiscal 1999 and
1998, respectively. We were profitable for fiscal 2000. Our ability to maintain
profitability on a quarterly basis in the future will depend on a variety of
factors, including our ability to increase our net sales, introduce new products
on a timely basis, secure sufficient wafer fabrication capacity and control our
operating expenses. Adverse developments with respect to these or other factors
could result in quarterly or annual operating losses in the future.

OUR SALES DEPEND ON SRAM PRODUCTS, AND A DECLINE IN AVERAGE SELLING PRICES OR
REDUCED DEMAND FOR THESE PRODUCTS COULD HARM OUR BUSINESS.

     A majority of our net sales are derived from the sale of SRAM products,
which are subject to unit volume fluctuations and declines in average selling
prices which could harm our business. For example, in the three months ended
June 31, 1998, our net sales decreased by 38% to $25.0 million from $40.7
million in the three months ended


                                       15


<PAGE>   18
March 31, 1998, principally due to a decrease in unit shipments of our SRAM
products. Further, we anticipate that the average selling prices of our existing
products will decline over time, although the rate of decline may fluctuate for
certain products. Such declines may not be offset by higher volumes or by higher
prices on newer products.

WE MAY NOT BE ABLE TO COMPENSATE FOR PRICE DECREASES IN OUR PRODUCTS.

     Competitive pricing pressures due to an industry-wide oversupply of wafer
capacity resulted in significant price decreases for our products during fiscal
1996 through fiscal 1999. Historically, average selling prices for semiconductor
memory products have declined, and we expect that average selling prices will
decline in the future. Our ability to maintain or increase revenues will depend
upon our ability to increase unit sales volume of existing products and
introduce and sell new products which compensate for the anticipated declines in
the average selling prices of our existing products.

     Declining average selling prices will also adversely affect our gross
margins and profits unless we are able to introduce new products with higher
margins or reduce our cost per unit. We may not be able to increase unit sales
volumes, introduce and sell new products or reduce our cost per unit.

SHIFTS IN INDUSTRY-WIDE CAPACITY MAY CAUSE OUR RESULTS TO FLUCTUATE. IN THE
PAST, SUCH SHIFTS HAVE RESULTED IN SIGNIFICANT INVENTORY WRITE-DOWNS.

     Shifts in industry-wide capacity from shortages to oversupply or from
oversupply to shortages may result in significant fluctuations in our quarterly
or annual operating results. The semiconductor industry is highly cyclical and
is subject to significant downturns resulting from excess capacity,
overproduction, reduced demand or technological obsolescence. These factors can
result in a decline in average selling prices and the stated value of inventory.
In fiscal 1998, we recorded inventory write-downs of $23.0 million. The
inventory write-downs were predominately for lower of cost or market accounting
on certain of our products, primarily SRAMs, and, to a lesser extent, excess
inventory.

     We also write down to zero carrying value inventory on hand in excess of
six months' estimated sales volumes to cover estimated exposures, unless
adjustments are made to the forecast based on management's judgments for newer
products, end of life products or planned inventory increases. In making such
judgments to write down inventory, management takes into account the product
life cycles which can range from 6 to 24 months, the stage in the life cycle of
the product, the impact of competitor's announcements and product introductions
on our products, and purchasing opportunities due to excess wafer capacity.

     We believe that six months is an appropriate period because it is difficult
to accurately forecast for a specific product beyond this time frame due to the
potential introduction of products by competitors, technology obsolescence or
fluctuations in demand. Our policy regarding excess inventory resulted in
inventory write-downs for excess inventory of approximately $5.4 million for
fiscal year 1998. Future additional inventory write-downs may occur due to lower
of cost or market accounting, excess inventory or inventory obsolescence.

IF WE ARE UNABLE TO OBTAIN AN ADEQUATE SUPPLY OF WAFERS, OUR BUSINESS WILL BE
HARMED.

     If we are unable to obtain an adequate supply of wafers from our current or
any alternative sources in a timely manner, our business will be harmed. To
date, our principal manufacturing relationship has been with TSMC, from which we
have obtained a majority of our wafers. We also receive wafers from Chartered
Semiconductor and UMC. Each of our wafer foundries also supplies wafers to other
integrated circuit companies, including certain of our competitors. Although we
have written commitments specifying wafer capacities from our suppliers, if
these suppliers experience manufacturing failures or yield shortfalls, choose to
prioritize capacity for other uses, or reduce or eliminate deliveries to us, we
may not be able to enforce fulfillment of the delivery commitments.
Additionally, we may not be able to qualify additional manufacturing sources for
existing or new products in a timely manner and we cannot be certain that other
manufacturing sources would agree to deliver an adequate supply of wafers to us.


                                       16


<PAGE>   19
FOUNDRY CAPACITY IS LIMITED AND WE MAY BE REQUIRED TO ENTER INTO COSTLY
LONG-TERM SUPPLY ARRANGEMENTS TO SECURE FOUNDRY CAPACITY.

     If we are not able to obtain additional foundry capacity as required, our
relationships with our customers would be harmed and our future sales would be
adversely impacted. In order to secure additional foundry capacity, we have
entered into and expect to enter into various arrangements with suppliers, which
could include:

     -    contracts that commit us to purchase specified quantities of silicon
          wafers over extended periods;

     -    investments in foundries;

     -    joint ventures;

     -    other partnership relationships with foundries;

     -    option payments or other prepayments to a foundry; or

     -    nonrefundable deposits with or loans to foundries in exchange for
          capacity commitments.

     We may not be able to make any such arrangements in a timely fashion or at
all, and such arrangements, if any, may not be on terms favorable to us.
Moreover, if we are able to secure foundry capacity, we may be obligated to
utilize all of that capacity or incur penalties. Such penalties may be expensive
and could harm our financial results.

ANY DOWNTURN IN THE MARKETS WE SERVE WOULD HARM OUR BUSINESS.

     A majority of our products are incorporated into products such as internet
access devices, networking equipment, and telecom/mobile communications devices.
These markets have from time to time experienced cyclical, depressed business
conditions, often in connection with, or in anticipation of, a decline in
general economic conditions. Such industry downturns have resulted in reduced
product demand and declining average selling prices. Our business would be
harmed by any future downturns in the markets that we serve.

WE DEPEND ON A SMALL NUMBER OF CUSTOMERS FOR A HIGH PERCENTAGE OF OUR SALES, AND
THE LOSS OF A SIGNIFICANT CUSTOMER COULD CAUSE A DECLINE IN OUR PROFITS.

     In fiscal 2000, no single customer accounted for over 10% of net sales.
However, in fiscal 2000, shipments for Cisco directly, or indirectly through
subcontractors, accounted for approximately 13% of net revenue. In fiscal 1999
and 1998, one customer, 3Com, accounted for approximately 20% and 19% of net
sales, respectively. As sales to these customers are executed pursuant to
purchase orders and no purchasing contract exists, these customers can cease
doing business with us at any time. We expect a significant portion of our
future sales to remain concentrated within a limited number of strategic
customers. We may not be able to retain our strategic customers, such customers
may cancel or reschedule orders, or in the event of canceled orders, such orders
may not be replaced by other sales. In addition, sales to any particular
customer may fluctuate significantly from quarter to quarter, and such
fluctuating sales could harm our business.

OUR PRODUCTS ARE COMPLEX AND COULD CONTAIN DEFECTS, WHICH COULD REDUCE SALES OF
THOSE PRODUCTS OR RESULT IN CLAIMS AGAINST US.

     We develop complex and evolving products. Despite testing by us and our
customers, errors may be found in existing or new products. This could result in
a delay in recognition or loss of revenues, loss of market share or failure to
achieve market acceptance. These defects may also cause us to incur significant
warranty, support and repair costs, divert the attention of our engineering
personnel from our product development efforts and could harm our relationships
with our customers. The occurrence of these problems could result in the delay
or loss of market acceptance of our products and would likely harm our business.
Defects, integration issues or other performance problems in our products could
result in financial or other damages to our customers or could lessen market
acceptance of our products. Our customers could also seek and obtain damages
from us for their losses. A product liability claim brought against us, even if
unsuccessful, would likely be time consuming and costly to defend.


                                       17


<PAGE>   20
STRONG COMPETITION IN THE SEMICONDUCTOR MEMORY MARKET MAY HARM OUR BUSINESS.

     The semiconductor memory market is intensely competitive and has been
characterized by an oversupply of product, price erosion, rapid technological
change, short product life cycles, cyclical market patterns and heightened
foreign and domestic competition. Certain of our competitors offer broader
product lines and have greater financial, technical, marketing, distribution and
other resources than us. We may not be able to compete successfully against any
of these competitors. Our ability to compete successfully in the high
performance memory market depends on factors both within and outside of our
control, including:

     -    real or perceived imbalances in supply and demand;

     -    product pricing;

     -    the rate at which OEM customers incorporate our products into their
          systems;

     -    the success of our customers' products;

     -    access to advanced process technologies at competitive prices;

     -    product functionality, performance and reliability;

     -    successful and timely product development;

     -    the supply and cost of wafers;

     -    achievement of acceptable yields of functional die;

     -    the gain or loss of significant customers; and

     -    the nature of our competitors and general economic conditions.

     In addition, we are vulnerable to technology advances utilized by
competitors to manufacture higher performance or lower cost products. We may not
be able to compete successfully in the future as to any of these factors. Our
failure to compete successfully in these or other areas could harm our business.

POTENTIAL INTELLECTUAL PROPERTY CLAIMS AND LITIGATION COULD SUBJECT US TO
SIGNIFICANT LIABILITY FOR DAMAGES AND COULD INVALIDATE OUR PROPRIETARY RIGHTS.

     In the semiconductor industry, it is not unusual for companies to receive
notices alleging infringement of patents or other intellectual property rights
of others. We have been, and from time-to-time expect to be, notified of claims
that we may be infringing patents, maskwork rights or copyrights owned by third
parties. For example, for a number of years we have been corresponding with a
large international semiconductor company regarding potential infringement of
certain of their patents by us and certain of our patents by them. Other
companies may pursue claims against us with respect to the alleged infringement
of patents, maskwork rights, copyrights or other intellectual property owned by
third parties. If it appears necessary or desirable, we may seek licenses under
patents that we are alleged to be infringing. Although patent holders commonly
offer such licenses, licenses may not be offered and the terms of any offered
licenses may not be acceptable to us.

     The failure to obtain a license under a key patent or intellectual property
right from a third party for technology used by us could cause us to incur
substantial liabilities and to suspend the manufacture of the products utilizing
the invention or to attempt to develop non-infringing products, any of which
could materially and adversely affect our business and operating results.
Furthermore, we may become involved in protracted litigation regarding the
alleged infringement by us of third party intellectual property rights or
litigation to assert and protect our patents or other intellectual property
rights. Any litigation relating to patent infringement or other intellectual
property matters could result in substantial cost and diversion of our resources
which could harm our business.

WE HAVE SIGNIFICANT INTERNATIONAL SALES AND RISKS OF OUR INTERNATIONAL
OPERATIONS COULD HARM OUR OPERATING RESULTS.

     In fiscal 2000, approximately 54% of our net sales was attributable to
customers located in the United States, 23% was attributable to customers
located in Europe and 23% was attributable to customers located in Asia. In
fiscal 1999, approximately 52% of our net sales was attributable to customers
located in the United States, 20% was attributable to customers located in
Europe and 28% was attributable to customers located in Asia. Accordingly, our
future operating results will also depend on general economic conditions in
Asia, Europe, and the United States. In addition, the markets for our products,
which are highly cyclical, may not continue to grow. We anticipate that sales to
international customers will continue to represent a significant percentage of
net sales.

     We are subject to the risks of conducting business internationally,
including:

     -    economic conditions in Asia, particularly Taiwan;

     -    changes in trade policy and regulatory requirements;

     -    duties, tariffs and other trade barriers and restrictions;

     -    the burdens of complying with foreign laws;

     -    foreign currency fluctuations; and

     -    political instability.

IF WE NEED TO MAKE PAYMENTS FOR UNUSED WAFER CAPACITY, OUR BUSINESS WILL BE
HARMED.

     We have minimum wafer purchase commitments with some of our foundry
partners in exchange for wafer capacity commitments. Should we fail to
reschedule or assign unneeded capacity, we will be required to make payments for
the unused capacity and our business would be harmed. We have agreed to make
certain annual purchases totaling, in aggregate, approximately $4.8 million
through 2001 from TSMC for additional capacity above the annual base capacity.
Wafer purchases in any given year are first applied to the base capacity and
then to our $4.8 million obligation. As a result, we could be forced to pay up
to $4.8 million even if we do not purchase the base capacity and additional
capacity for which we have contracted. We also have minimum purchase obligations
to TSMC related to WaferTech LLC, a business venture in which we are an
investor. We are obligated to purchase from WaferTech or TSMC a minimum of 2.3%
of WaferTech's installed capacity. Our obligations related to WaferTech
terminate upon the completion of the sale of our interest in WaferTech to TSMC.
Although we have rights to reschedule or assign capacity to other parties, we
may not be able to successfully do so.

WE DEPEND ON OUR ABILITY TO ATTRACT AND RETAIN OUR KEY TECHNICAL AND MANAGEMENT
PERSONNEL.

     Our success depends upon the continued service of key technical and
management personnel, including Jimmy S.M. Lee, Chairman and Chief Executive
Officer, and on our ability to continue to attract, retain and motivate
qualified personnel, particularly experienced circuit designers and process
engineers. The competition for such employees is intense. We have no employment
contracts or key person life insurance policies with or for any of our executive
officers. The loss of the service of one or more of our key personnel could
materially and adversely affect our business and operating results.

OUR STOCK PRICE IS EXPECTED TO BE VOLATILE.

     The trading price of our common stock has been and is expected to be
subject to wide fluctuations in response to:

     -    quarter-to-quarter variations in our operating results;

     -    comments or recommendations issued by analysts who follow us, our
          competitors or the semiconductor industry and other events or factors;


                                       19


<PAGE>   22
     -    aggregate valuations and movement of stocks in the broader
          semiconductor industry;

     -    announcements of new products, strategic relationships or acquisitions
          by us or our competitors;

     -    increases or decreases in wafer capacity;

     -    general conditions or cyclicality in the semiconductor industry or the
          end markets that we serve;

     -    governmental regulations, trade laws and import duties;

     -    litigation;

     -    new or revised earnings estimates;

     -    announcements of technological innovations by us or our competitors;

     -    additions or departures of senior management; and

     -    other events or factors many of which are beyond our control.

     In addition, stock markets have experienced extreme price and trading
volume volatility in recent years. This volatility has had a substantial effect
on the market prices of securities of many high technology companies for reasons
frequently unrelated to the operating performance of the specific companies.
These broad market fluctuations may adversely affect the market price of our
common stock.

ITEM 7a. MARKET RISK DISCLOSURES

     We develop products in the United States and sell them worldwide. As a
result, our financial results could be affected by factors such as changes in
foreign currency exchange rates or weak economic conditions in foreign markets.
Since our sales are currently priced in U.S. dollars and are translated to local
currency amounts, a strengthening of the dollar could make our products less
competitive in foreign markets. Interest income is sensitive to changes in the
general level of U.S. interest rates, particularly since our investments are in
short-term instruments calculated at variable rates.

     We established policies and business practices regarding our investment
portfolio to preserve principal while obtaining reasonable rates of return
without significantly increasing risk. We place investments with high credit
quality issuers according to our investment policy. We do not use derivative
financial instruments in our investment portfolio. All investments are carried
at cost, which approximates market value. Due to the short-term nature of our
investments and the immaterial amount of our debt obligation, we believe that
there is no material exposure to interest fluctuation. Therefore, no
accompanying table has been provided.

                REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS


The Board of Directors and Stockholders
Integrated Silicon Solution, Inc.

     We have audited the accompanying consolidated balance sheets of Integrated
Silicon Solution, Inc. as of September 30, 2000 and 1999, and the related
consolidated statements of operations, comprehensive income, stockholders'
equity, and cash flows for each of the three years in the period ended September
30, 2000. Our audits also included the financial statement schedule listed in
the Index at Item 14(a). These financial statements and schedule are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements and schedule based on our audits.

     We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Integrated Silicon Solution, Inc. at September 30, 2000 and 1999, and the
consolidated results of its operations and its cash flows for each of the three
years in the period ended September 30, 2000, in conformity with accounting
principles generally accepted in the United States. Also in our opinion, the
related financial statement schedule, when considered in relation to the basic
financial statements taken as a whole, presents fairly in all material respects
the information set forth therein.

                   Notes to Consolidated Financial Statements

NOTE 1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION

     Integrated Silicon Solution, Inc. (the "Company") was incorporated in
California on October 27, 1988 and reincorporated in Delaware on August 9, 1993.

BASIS OF PRESENTATION

     The accompanying consolidated financial statements include the accounts of
Integrated Silicon Solution, Inc. and its majority owned subsidiaries, after
elimination of all significant intercompany accounts and transactions.

     The Company's financial results for fiscal 2000 reflect accounting for
Integrated Circuit Solution, Inc., ("ICSI") and NexFlash Technologies, Inc.
("NexFlash") on the equity basis and include its percentage share of the results
of ICSI's and NexFlash's respective operations. At September 30, 2000, the
Company owned approximately 39% of ICSI. Prior to the quarter ended March 31,
1999, the Company's ownership of ICSI exceeded 50% and its financial results
were consolidated with those of ICSI. Effective with the quarter ending March
31, 1999, the Company accounted for ICSI on the equity basis and included in its
financial statements its percentage share of ICSI's financial results. In
October 1998, the Company transferred its Flash memory business to NexFlash, and
presently owns approximately 32% of that company. In fiscal 1999, the Company
accounted for NexFlash on the equity basis and included in its financial
statements its percentage share of NexFlash's financial results. The Company's
financial results for fiscal year 1998 include the results of the operations of
NexFlash and ICSI on a consolidated basis.

CASH EQUIVALENTS AND SHORT -TERM INVESTMENTS

     The Company considers all highly liquid investments with a maturity of
three months or less at the date of purchase to be cash equivalents.

     Under Statement of Financial Accounting Standards No. 115, "Accounting for
Certain Investments in Debt and Equity Securities" all affected debt securities
must be classified as held-to-maturity, trading, or available-for-sale and
equity securities must be classified as trading or available-for-sale.
Management determines the appropriate classification of debt and equity
securities at the time of purchase and reevaluates such designation as of each
balance sheet date.

     At September 30, 2000 and 1999, all debt and equity securities were
designated as available-for-sale. Available-for-sale securities are carried at
fair value, with unrealized gains and losses, net of tax, reported in a separate
component of stockholders' equity. The amortized cost for available-for-sale
debt securities is adjusted for the amortization of premiums and accretion of
discounts to maturity. Such amortization is included in investment income.
Realized gains and losses and declines in value judged to be
other-than-temporary on available-for-sale securities are included in investment
income. The cost of securities sold is based on the specific identification
method. Interest and dividends on securities classified as available-for-sale
are included in investment income. At September 30, 2000 and 1999, the cost of
these securities approximated the fair value (quoted market price) and the
amount of unrealized gain or loss was not significant. Except for the gains
(losses) recognized on the sales of securities of ICSI, WaferTech, and UICC (see
Note 17), there were no gains or losses on the sale of securities for the years
ended September 30, 2000, 1999 and 1998.

INVENTORIES

     Inventories are stated at the lower of cost (first-in, first-out) or
market. The Company's inventory valuation process is done on a part-by-part
basis. Lower of cost or market adjustments, specifically identified on a
part-by-part basis, reduce the carrying value of the related inventory and take
into consideration reductions in sales prices, excess inventory levels and
obsolete inventory. Once established, these adjustments are considered permanent
and are not reversed until the related inventory is sold or disposed.

                   Notes to Consolidated Financial Statements

PROPERTY, EQUIPMENT, AND LEASEHOLD IMPROVEMENTS

     Property, equipment, and leasehold improvements are stated at cost.
Equipment under capital leases is stated at the present value of minimum lease
payments at the beginning of the lease term. Depreciation and amortization are
computed using the straight-line method, based upon the shorter of the estimated
useful lives ranging from three to seven years, or the lease term of the
respective assets, if applicable.

ACCUMULATED COMPREHENSIVE INCOME (LOSS)

     The accumulated comprehensive income (loss) component within the
stockholders' equity section of the Balance Sheet is comprised entirely of
foreign currency translation adjustments.

REVENUE RECOGNITION

     The Company recognizes revenue to non-distributor customers upon passage of
title. The Company provides for estimated sales returns on sales to these
customers. Sales made to distributors, under terms allowing certain rights of
return and price protection on unsold merchandise held by the distributor, are
deferred until the merchandise is sold by the distributor.

FOREIGN CURRENCY TRANSLATION

     The Company uses the local currency as its functional currency for all
foreign subsidiaries. Translation adjustments, which result from the process of
translating foreign currency financial statements into U.S. dollars, are
included in the accumulated comprehensive income component of stockholder's
equity.

USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

CONCENTRATION OF CREDIT RISK

     The Company operates in one business segment, which is to design, develop,
and market high performance SRAM, DRAM, and other memory products. The Company
markets and distributes its products on a worldwide basis, primarily to original
equipment manufacturers, contract manufacturers, and distributors. The Company
performs ongoing credit evaluations of its customers' financial condition and
generally requires no collateral. In fiscal 2000 no single customer accounted
for over 10% of net sales. However, shipments for Cisco directly, or indirectly
through subcontractors, accounted for approximately 13% of net revenue. In
fiscal 1999 and 1998, one customer, 3Com, accounted for approximately 20% and
19% of net sales, respectively.

     The Company maintains cash, cash equivalents, and short-term investments
with various financial institutions. The Company's investment policy is designed
to limit exposure to any one institution. The Company performs periodic
evaluations of the relative credit standing of those financial institutions that
are considered in its investment strategy. The Company is exposed to credit risk
in the event of default by the financial institutions or issuers of investments
to the extent of the amount recorded on the balance sheet. To date, the Company
has not incurred losses related to these investments.

SEMICONDUCTOR INDUSTRY RISKS

     To date the Company has derived substantially all of its revenues from the
sale of SRAM products. The Company has diversified into other product areas,
such as low and medium density DRAMs serial EEPROMs, certain microcontrollers,
and voice recording chips. However, a substantial majority of the Company's
revenue is still derived from SRAM products and, if the market for SRAM products
should decline, such decline would have a material adverse affect on the
Company's financial performance.

     The semiconductor industry is characterized by rapid technological change,
intense competitive pressure and cyclical market patterns. The Company's results
of operations are affected by a wide variety of factors, including


                                       29


<PAGE>   32
                   Notes to Consolidated Financial Statements

declines in average selling prices of our products, oversupply of memory
products in the market, failure to introduce new products and to implement
technologies on a timely basis, the timing and announcement of new product
introductions by the Company and its competitors, market acceptance of the
Company's and its customers' products, the failure to anticipate changing
customer product requirements, fluctuations in manufacturing yields, disruption
in delivery and order fulfillment, and disruption in the supply of wafers or
assembly services. Other factors include changes in product mix, seasonal
fluctuations in customer demand for the Company's products, the timing of
significant orders, increased expenses associated with new product introductions
or process changes, the ability of customers to make payments to the Company,
increases in material costs, increases in antidumping duties, increases in costs
associated with the expansion of sales channels, increases in general and
administrative expenses, and certain production and other risks associated with
using independent manufacturers. As a result, the Company may experience
substantial period-to-period fluctuations in future operating results due to the
factors mentioned above or other factors.

NET INCOME (LOSS) PER SHARE

     Basic net income (loss) per share and diluted net income (loss) per share
is computed using the weighted number of common shares outstanding during the
period. Diluted net income (loss) per share is computed using the weighted
average number of common and dilutive common equivalent shares outstanding, if
applicable, during the period. Common equivalent shares consist of the shares
issuable upon the exercise of stock options and warrants under the treasury
stock method.

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

     In December 1999, the Securities and Exchange Commission ("SEC") issued
Staff Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition", which
provides guidance on the recognition, presentation and disclosure of revenue in
financial statements filed with the SEC. SAB 101 outlines the basic criteria
that must be met to recognize revenue and provides guidance for disclosures
related to revenue recognition policies. The Company will be required to adopt
the provisions of SAB 101 in the fourth quarter of fiscal 2001. The Company
believes that its revenue recognition policy is in compliance with the
provisions of SAB 101 and that the adoption of SAB 101 will have no material
effect on its financial position or results of operations.

     In June 1998, the Financial Accounting Standards Board issued Statement
133, ("FAS 133") "Accounting for Derivative Instruments and Hedging Activities",
which is required to be adopted in fiscal years beginning after June 15, 2000.
The Company will be required to adopt the provisions of FAS 133 in the first
quarter of fiscal 2001. Because of the Company's minimal use of derivatives,
management does not anticipate that the adoption of the new Statement will have
a significant effect on the Company's earnings or its financial position.

     In March 2000, the Financial Accounting Standards Board issued FASB
Interpretation No. 44 ("FIN 44"), "Accounting for Certain Transactions Involving
Stock Compensation -- an Interpretation of APB Opinion No. 25." FIN 44 clarifies
the application of APB Opinion No. 25 and, among other issues, clarifies the
following: the definition of an employee for purposes of applying APB Opinion
No. 25: the criteria for determining whether a plan qualifies as a
noncompensatory plan; the accounting consequences of various modifications to
the terms of the previously fixed stock options or awards; and the accounting
for an exchange of stock compensation awards in a business combination. FIN 44
was effective July 1, 2000, but certain conclusions in FIN 44 cover specific
events that occurred after either December 15, 1998 or January 12, 2000. The
adoption of FIN 44 did not have a material impact on the Company's financial
position or results of operations.

RECLASSIFICATION OF PRIOR YEAR BALANCES

     Certain reclassifications have been made to prior year's financial
statements to conform to the current year presentation.

NOTE 9. STOCK PLANS

1989 STOCK OPTION PLAN

     During 1989, the Company adopted a stock option plan (the "Plan") that
provides for the grant of incentive stock options to employees and nonstatutory
stock options to our employees, consultants and nonemployee directors.

     Incentive stock options and nonstatutory options granted under the Plan
have five or ten-year terms. All incentive stock option grants and nonstatutory
stock option grants must be at prices of at least 100% and 85%, respectively, of
the fair market value of the stock on the date of grant, as determined by the
Board of Directors.

     The options are exercisable as determined by the Board of Directors.
Generally, the stock options vest ratably over a four-year period. The options
expire upon the earlier of five or ten years from the date of grant or 30 days
following termination of employment. Options to purchase 795,000 shares, 920,000
shares, and 1,120,000 shares were exercisable as of September 30, 2000, 1999,
and 1998, respectively.

     In the event of certain changes in control of ISSI, the Plan requires that
each outstanding option be assumed or an equivalent option substituted by the
successor corporation; however, if such successor refuses to assume the then
outstanding options, the Plan provides for the full acceleration of the
exercisability of all outstanding options.

1996 STOCK OPTION PLAN

     On October 18, 1996, the Company adopted a stock option plan (the "1996
Plan") that provides for the grant of non-statutory stock options to our
non-executive employees and consultants.

     Under the terms of the plan, the exercise price and exercise period of
stock option grants is determined by the Board of Directors on the date of
grant. Generally, the stock options vest ratably over a four year period. The
options expire upon the earlier of ten years from the date of grant or 30 days
following termination of employment or consultancy. Options to purchase 286,000
shares, 493,000 shares, and 430,000 shares were exercisable as of September 30,
2000, 1999, and 1998, respectively.

     In the event of certain changes in control of ISSI, the 1996 Plan requires
that each outstanding option be assumed or an equivalent option substituted by
the successor corporation; however, if such successor refuses to assume the then
outstanding options, the 1996 Plan provides for the full acceleration of the
exercisability of all outstanding options.

1998 STOCK OPTION PLAN

     The Board of Directors and stockholders approved the 1998 Stock Option Plan
(the "1998 Plan") in October 1998 and January 1999, respectively. The 1998 Plan
provides for the grant of incentive stock options to employees and nonstatutory
stock options to employees, consultants and nonemployee directors of ISSI. Stock
purchase rights may also be granted under the 1998 Plan.

     Under the terms of the 1998 Plan, the exercise price and exercise period of
non-statutory stock option grants is determined by the Board of Directors on the
date of grant. All incentive stock option grants must be at prices of at least
100% of the fair market value of the stock on the date of grant, as determined
by the Board of Directors. Generally, the stock options vest ratably over a four
year period. The options expire upon the earlier of ten years from the date of
grant or 90 days following termination of employment or consultancy, unless
specified otherwise in the option agreement. Options to purchase 67,000 shares
were exercisable as of September 30, 2000. No options to purchase shares were
exercisable as of September 30, 1999.

     In the event of certain changes in control of ISSI, the 1998 Plan requires
that each outstanding option be assumed or an equivalent option substituted by
the successor corporation; however, if such successor refuses to assume the then
outstanding options, the 1998 Plan provides for the full acceleration of the
exercisability of all outstanding options.

1995 DIRECTOR STOCK OPTION PLAN

     The Board of Directors and stockholders approved the 1995 Director Stock
Option Plan (the "Director Plan") in December 1995 and January 1996,
respectively. Under the terms of the Director Plan, 125,000 shares of Common
Stock were authorized for issuance. Each director who has been a non-employee
director for at least six months will automatically receive a non-statutory
option to purchase 2,500 shares of Common Stock upon such director's annual
reelection to the Board by the stockholders. Options to purchase 32,000 shares,
38,000 shares, and 26,000 shares were exercisable at September 30, 2000, 1999,
and 1998, respectively.

Approximately 1,949,000 shares with an aggregate exercise price of approximately
$17.0 million were repriced to an exercise price of $3.1562 per share. In
connection with the repricing, certain vesting and exercise rights were
surrendered.

STOCK-BASED COMPENSATION

     As permitted under FAS 123, the Company has elected to follow APB 25 and
related Interpretations, in accounting for stock-based awards to employees.
Under APB 25, the Company generally recognized no compensation expense with
respect to such awards.

     Pro forma information regarding net income (loss) and earnings (loss) per
share is required by FAS 123 for awards granted or modified after September 30,
1995, as if the Company had accounted for its stock-based awards to employees
under the fair value method of FAS 123. The fair value of the Company's
stock-based awards to employees was estimated using a Black-Scholes option
pricing model. The Black-Scholes model requires the input of highly subjective
assumptions including the expected stock price volatility. Because the Company's
stock-based awards to employees have characteristics significantly different
from those of traded options, and because changes in the subjective input
assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its stock-based awards to employees. The fair value
of the Company's stock-based awards to employees was estimated assuming no
expected dividends and the following weighted-average assumptions:

     The weighted-average fair value of options granted at market value during

The weighted-average fair value of employee stock purchase rights during fiscal
2000, 1999, and 1998 was $4.81, $3.04, and $3.89 per share, respectively.

                   Notes to Consolidated Financial Statements

     For pro forma purposes, the estimated fair value of the Company's
stock-based awards to employees is amortized over the options' vesting period
(for options) and the six-month purchase period (for stock purchases under the
ESPP). The Company's pro forma information for the years ended September 30, is
as follows (in thousands, except for income (loss) per share information):

</TABLE>

     Because FAS 123 is applicable only to awards granted subsequent to
September 30, 1995, its pro forma effect was not fully reflected until fiscal
1999. Due to the subjective nature of the assumptions used in the Black-Scholes
model, the proforma net income (loss) and proforma net income (loss) per share
may not be indicative of the effects on net income (loss) and net income (loss)
per share in future years.

NOTE 10.  1998 ISSI-TAIWAN STOCK PLAN

     On October 29, 1998, the Company adopted the 1998 ISSI-Taiwan Stock Plan
(the "Taiwan Stock Plan") that provides for the grant of non-statutory stock
options in the common stock of ICSI to the employees, consultants, and directors
of the Company. Upon exercise, if any, the Company would sell its shares in ICSI
to the optionee. Under terms of the Taiwan Stock Plan, the maximum aggregate
number of shares of ICSI stock which may be optioned and sold is 12.0 million.
This represents approximately 10% of the outstanding shares of ICSI.

     Under the terms of the Taiwan Stock Plan, the exercise price, which is
deemed to be the fair value of ICSI at the date of grant, and the exercise
period of the non-statutory stock option grants are determined by the Board of
Directors on the date of grant. Generally, the stock options vest one-third
annually on the anniversary of the date of grant. The options expire upon the
earlier of ten years from the date of grant or 30 days following termination of
employment or consultancy. During fiscal 2000, options to purchase 3,110,000
shares of ICSI stock were exercised. Options to purchase 6,910,000 shares of
ICSI stock were outstanding at September 30, 2000, of which 315,000 were
exercisable. Options to purchase 10,374,000 shares of ICSI stock were
outstanding, at September 30, 1999, none of which were exercisable.

     If within twelve months of certain changes of control of ISSI an optionee's
status as an employee or consultant of ISSI is terminated without cause, the
Taiwan Stock Plan provides for full acceleration of the exercisability of all
outstanding options.

     As of September 30, 2000 the Company had federal net operating loss
carryforwards of approximately $16,100,000. The Company has federal research and
development credit carryforwards, foreign tax credit carryforwards and
alternative minimum tax credit carryforwards of approximately $3,340,000,
$3,823,000, and $773,000, respectively. The Company also has state research and
manufacturers' investment tax credit carryforwards of approximately $700,000
each. The federal net operating loss, foreign tax credit and state
manufacturer's credit carryforwards will expire at various dates beginning in
2001 through 2020, if not utilized. The California research and development
credit can be carried forward indefinitely.

     Utilization of the net operating loss carryforwards and credits may be
subject to a substantial annual limitation due to the ownership change
limitations provided by the Internal Revenue Code of 1986, as amended, and
similar state provisions. The annual limitation may result in the expiration of
net operating losses and credits before utilization.

     Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amount used for income tax purposes. Significant components of
deferred taxes consisted of the following at September 30:

     Management has established a valuation allowance for a portion of the gross
deferred tax assets based on management's expectations of future taxable income
and the actual taxable income during the three years ended September 30, 2000.
The valuation allowance for deferred tax assets decreased by $6,395,000 in 2000
and $8,981,000 in 1999. Approximately $6,200,000 of the valuation allowance is
attributable to tax benefits of stock option deductions which will be credited
to paid in capital when recognized.

     Transfers between geographic areas are accounted for at amounts which are
generally above cost and consistent with rules and regulations of governing tax
authorities. Such transfers are eliminated in the consolidated financial
statements.

     Long-lived assets by geographic area are those assets used in the Company's
operations in each area.

     Net foreign currency transaction gains (losses) of approximately $(40,000),
$594,000, and $(3,188,000), for the years ended September 30, 2000, 1999, and
1998, respectively, were primarily the result of the settlement of intercompany
transactions and are included in the determination of net income (loss).

NOTE 14.  COMMITMENTS AND CONTINGENCIES

PATENTS AND LICENSES

     In the semiconductor industry, it is not unusual for companies to receive
notices alleging infringement of patents or other intellectual property rights
of others. The Company has been, and from time-to-time expects to be, notified
of claims that it may be infringing patents, maskwork rights or copyrights owned
by third parties. For example, for a number of years the Company has been
corresponding with a large international semiconductor company regarding
potential infringement of certain of their patents by us and certain of our
patents by them. Other



                                       39
<PAGE>   42

                   Notes to Consolidated Financial Statements

companies may pursue claims against the Company with respect to the alleged
infringement of patents, maskwork rights, copyrights or other intellectual
property owned by third parties. If it appears necessary or desirable, the
Company may seek licenses under patents that it is alleged to be infringing.
Although patent holders commonly offer such licenses, licenses may not be
offered and the terms of any offered licenses may not be acceptable to the
Company. The failure to obtain a license under a key patent or intellectual
property right from a third party for technology used by the Company could cause
it to incur substantial liabilities and to suspend the manufacture of the
products utilizing the invention or to attempt to develop non-infringing
products, any of which could materially and adversely affect the Company's
business and operating results. Furthermore, there can be no assurance that the
Company will not become involved in protracted litigation regarding its alleged
infringement of third party intellectual property rights or litigation to assert
and protect its patents or other intellectual property rights. Any litigation
relating to patent infringement or other intellectual property matters could
result in substantial cost and diversion of the Company's resources which could
materially and adversely affect the Company's business and operating results.

LITIGATION

     In April 1998, the U.S. Department of Commerce ("DOC") published an
antidumping duty order on imports of SRAMs from Taiwan, from where the Company
currently imports a majority of its SRAMs. As a consequence of this antidumping
duty order, the Company is required to post a cash deposit on imports of Taiwan
fabricated SRAM wafers or devices at the ad valorem rate of 7.56%.

     On April 28, 2000, Micron Technology Inc. ("Micron") requested an
administrative review of the Company's Taiwan fabricated SRAMs for the period
from April 1, 1999 through March 31, 2000. For entries during this period, the
cash deposits could be returned to the Company or, alternatively, the Company
could forfeit amounts deposited and owe duties and interest in addition to the
amounts deposited, depending on results of the DOC administrative review. The
final results of the review are expected in the year 2001 and will establish a
new deposit rate for subsequent entries, which may be higher or lower than the
current rate.

     The Company has retained legal counsel to defend its interests in the
antidumping proceedings. In addition, respondents (including ISSI) have
challenged certain aspects of the antidumping determination in federal court
proceedings. On August 29, 2000, pursuant to an appeal by ISSI and other
respondents, the U.S. Court of International Trade affirmed the International
Trade Commission ("ITC") decision to reverse the ITC's earlier ruling supporting
the imposition of antidumping duties and rule instead in favor of respondents.
This decision by the Court of International Trade has been appealed by Micron to
the Federal Circuit Court of Appeals. If such appeal is not successful, the
antidumping case will be terminated, the order will be revoked, and the Company
will be entitled to a full refund of cash deposits. Pending resolution of the
appeal, the DOC will continue to administer the antidumping order.

     Duties calculated and assessed by the government could have a material
adverse affect on the Company's gross margins and profits. Any reviews or
proceedings might not mitigate or eliminate antidumping duties.

LEASES

     The Company leases its facilities under operating lease agreements that
expire at various dates through 2007. The Company entered into a ten year lease
effective December 1, 1996 for its headquarters facility in Santa Clara,
California. The Company subleases to NexFlash approximately 9,000 square feet on
a month to month lease. Additionally, the Company subleases approximately 24,000
square feet to a third party. The sublease expires in March 2003. Minimum rental
commitments under these leases are as follows (in thousands):

     Total rental expense for the years ended September 30, 2000, 1999, and
1998, was approximately $1,034,000 (net of sublease income of $634,000),
$1,050,000 (net of sublease income of $630,000), and $1,078,000 (net of sublease
income of $375,000), respectively.

COMMITMENTS TO WAFER FABRICATION FACILITIES

     In August 2000, the Company entered into a wafer fabrication facility
investment agreement with SMIC, a foundry currently under construction in
Shanghai, China. Under the terms of this agreement, the Company has committed to
invest $30.0 million. The Company has received certain capacity commitments from
SMIC. As of September 30, 2000, the Company had invested $4.6 million in this
foundry, and $14.3 million and $11.1 million are expected to be invested in
fiscal years 2001 and 2002, respectively.

     In June 1996, the Company entered into a business venture called WaferTech,
LLC with TSMC, Altera, Analog Devices, and private investors to build a wafer
fabrication facility in Camas, Washington. The Company agreed to invest $31.2
million for a 4% equity interest in the venture and, as of September 30, 1998,
all of this amount had been paid. In January 1999, the Company sold
approximately 33% of its investment in WaferTech to TSMC for $10.0 million. The
Company retains a 2.67% interest in WaferTech. In October 1999, the major
investors in WaferTech made an additional pro-rata investment in WaferTech. The
Company's pro-rata amount of $2.7 million was invested along with the other
partners. The Company's investment in WaferTech as of September 30, 2000 was
$23.5 million. In November 2000, the Company agreed to sell its interest in
WaferTech to TSMC for approximately $40.0 million. The transaction is expected
to close by December 31, 2000. The Company has minimum purchase obligations to
TSMC related to WaferTech. The Company is obligated to purchase from WaferTech
or TSMC a minimum of 2.3% of WaferTech's installed capacity. The Company's
obligations related to WaferTech terminate upon the completion of the sale of
its interest in WaferTech to TSMC.

     In fiscal 1995, the Company agreed to certain minimum wafer purchase
commitments with TSMC in exchange for wafer capacity commitments through 2001.
The Company also agreed to make certain annual payments to TSMC, the remaining
amount of which totals approximately $4.8 million through 2001, for additional
capacity above the annual base capacity. Wafer purchases in any given year are
first applied to the base capacity and then to our $4.8 million obligation. As a
result, the $4.8 million may be subject to forfeiture if the Company does not
purchase the base capacity and additional capacity for which it has contracted.
The Company does not currently expect to forfeit any amounts or incur any losses
associated with these capacity agreements. Although the Company has rights to
re-schedule or assign capacity to another party, there can be no assurance that
such re-schedule or assignment would be successfully accomplished. Should the
Company fail to re-schedule or assign unneeded capacity, its business and
operating results could be adversely affected.

NOTE 15.  EMPLOYEE BENEFIT PLAN

     In August 1992, the Company established a defined contribution retirement
plan with 401(k) plan features. The plan covers all United States employees 18
years and older. Employees may make contributions by a percentage reduction in
their salaries, up to $10,500 for 2000. The Company elected to make no
contributions during the years ended September 30, 2000, 1999, and 1998.
Administrative expenses relating to the plan are insignificant.

NOTE 17.  TRANSACTIONS

     On December 3, 1997, the Company completed its acquisition of Nexcom
Technology, Inc. ("Nexcom") in exchange for the issuance of 772,693 shares of
Common Stock, $0.5 million in cash, and the assumption of $1.2 million of net
liabilities (total consideration of approximately $8.5 million). The transaction
was accounted for as a purchase and resulted in an in-process technology charge
of approximately $7.1 million in the Company's December 31, 1997 quarter. Nexcom
was formed in 1990 and was engaged primarily in the research and development of
non-volatile flash memory technology.

     On June 29, 1998, the Company sold approximately 46% of ICSI to a group of
private investors. The price was privately negotiated between the parties. Cash
proceeds from the transaction totaled $35.5 million net of withholding and
transaction taxes. The transaction resulted in a pre-tax gain of $10.5 million
which was recorded in our June 30, 1998 quarter.

     Effective October 1, 1998, the Company transferred certain employees and
joint ownership of certain patents and related Flash technology to NexFlash.
ISSI and NexFlash jointly own existing Flash related patents, and NexFlash
continues the development of Flash products. The Company owns approximately 32%
of NexFlash, and ICSI owns approximately 17%. ISSI's President is Chairman of
NexFlash. In connection with the NexFlash transaction, the Company issued
warrants to purchase an aggregate of 981,659 shares of ISSI Common Stock at an
exercise price of $3.76 per share, the fair market value at date of grate, to
the NexFlash investors. The Company determined the fair value of the warrants
using the Black-Scholes valuation model assuming a fair value of the common
stock of $4.44 per share, risk free interest rate of 4.43%, volatility factor of
70%, and a life of two years. During fiscal 2000, the Company issued 457,029
shares of its common stock pursuant to the exercise of warrants to purchase
582,660 shares of its common stock. All remaining unexercised warrants expired
on November 4, 2000.

     In December 1998, the Company sold an additional 20% of its holdings in
ICSI to a group of private investors resulting in a pre-tax gain of $1.2
million. Proceeds from the transaction net of withholding and transaction taxes
totaled $6.6 million (including cash of $4.3 million and notes receivable of
$2.3 million). Effective December 31, 1998, the Company owned approximately 43%
of ICSI and accounted for ICSI on the equity basis. ICSI was consolidated in the
accompanying statement of operations until December 31, 1998 when the additional
20% of the Company's holdings were sold. The accompanying consolidated balance
sheets as of September 30, 2000 and September 30, 1999 reflects ICSI as an
investment accounted for on the equity basis.

     In December 1998, the Company agreed to sell approximately 33% of its
investment in WaferTech to TSMC for approximately $10.0 million. The transaction
was completed in January 1999, and the Company retained a 2.67% interest in
WaferTech. The Company recorded a loss of approximately $0.4 million in the
March 1999 quarter related to this transaction.

     In April 1999, the Company agreed to sell its investment in UICC to UMC for
its original acquisition cost. The Company recorded a gain of approximately $1.8
million in the June 1999 quarter related to this transaction. The gain resulted
from adjustments to the original acquisition value for fluctuations in the New
Taiwanese Dollar.

     On October 13, 1999, the major investors in WaferTech, which include TSMC,
Altera, Analog Devices, and ISSI, made pro-rata investments in WaferTech. The
Company's pro-rata amount of $2.7 million was invested along with the other
partners. The Company's investment in WaferTech as of September 30, 1999 was
$20.8 million. After the October 1999 additional investment, the Company's total
investment in WaferTech is $23.5 million.


NOTE 18.  RELATED PARTY TRANSACTIONS
