Industrial USB3.1 Gen1 USB Flash Disk (SLC Type)2.4. Error Detection and Correction
The hardware Error Correction Coding (ECC) engine executes parity generation and error
detection/correction features and enhances decoding throughput and data reliability.
With multi-mode correction capability up to 96 bits, the powerful ECC engine is able to support
the latest generation NAND.

2.5. Wear-LevelingWear Levelling (WL) is used to systematically utilize all Flash blocks of the system equally interms of consuming their individual write-erase-cycle endurance budget. hyMap® supports
dynamic, static, and global Wear levelling. Dynamic WL requires no copy-overhead but alone
would be limited to blocks not containing data. Static WL includes also those blocks containing
data. Static data is relocated if needed. This WL activity is triggered at predefined thresholdlevels. Also, these routines are executed in the background and interrupted in case of higher
priority host commands.
Global WL refers to the procedure of involving all blocks (user blocks, management blocks, freeblocks) of a device and is not limited to flash chips for instance. Generally, the WL algorithm
selects a block with the lowest erase count from a pool of unused blocks to be written to(dynamic WL). At some point formerly used blocks enter the pool of unused blocks again as aresult of the garbage collection. When a block enters the pool of unused blocks, its erase countervalue is compared with the lowest erase counter value of all used blocks (global WL). If thedifference exceeds a configurable threshold, the data of a used block with lowest erase count is
moved into the block that just became unused and the used block with lowest erase count enters
the pool of unused blocks instead (static WL).
The threshold is configurable and defines the granularity and the spread between the block(s)with the “lowest erase counts” and the “highest erase counts”. Within hyMap® this is called
Adaptive Wear Levelling.

2.6. Bad Blocks Management
Bad Blocks are blocks that contain one or more invalid bits whose reliability are not guaranteed.
The Bad Blocks may be presented while the USB Flash Disk is shipped or may generate during
the lifetime of the USB Flash Disk. When the Bad Blocks is detected, it will be flagged, and not
be used anymore. The USB Flash Disk implement Bad Blocks management and replacement,Error Correct Code to avoid data error occurred. The functions will be enabled automatically totransfer data from Bad Blocks to spare blocks, and correct error bit. After the reserved block lessthan threshold of each channel, the USB Flash Disk will be locked, and cannot be read andwritten anymore.

Industrial USB3.1 Gen1 USB Flash Disk (SLC Type)2.7. Power Fail Robustness
Generally, ADTEC UFD P-Series proved voltage sensing capability and as soon as a power
down is recognized, the controller is reset, and the flash is write-protected. A log of all recent
flash transactions is kept. Should the latest data be corrupt, the controller will recover the latest
valid entry before that last failed write.

2.8. No external DRAM no capacitor
All mapping information is reliably stored on the flash. No external DRAM is used to store vital
mapping information in volatile memory and no external capacitor is needed to make sure that
DRAM content is stored in the Flash in case of a power fail situation.
Hence, there is no additional reliability risk and endurance impact related to implementing these
additional components.

2.9. Reliable Write
hyMap® is targeted to making SLC Flash as reliable as possible. Since two logical SLC Flashpages are physically correlated, it is possible to destroy data of an older page by writing anothernew one within the same block (paired pages).
hyMap® applies Reliable Write to cope with this occurrence and in order to make SLC power-failsafe.

2.10. Mean Time between Failures (MTBF)
Failure Rate: The total number of failures within an item population, divided by the total numberof life units expended by that population, during a particular measurement interval under statedcondition.
Mean Time between Failures (MTBF): A basic measure of reliability for repairable items: Themean number of life units during which all parts of the item perform within their specified limits,
during a particular measurement interval under stated conditions.
