sata - disk module 4 ap sdm xxxx x 5 an - acm x x 9 ? 20 1 2 apacer technology inc. rev . 1. 2 5 . flash mana gement 5 . 1 error correction / d etection sdm 4 - m implements a hardware ecc scheme, based on the bch algorithm. it can detect and correct up to 16 bits or 2 4 bits error in 1k bytes. 5 .2 bad block management although bad blocks on the flash media are already ide ntified by the flash manufactur er , they can also be accumulated over time during operation. sdm 4 - m s controller maintain s a table that lists those normal blocks with disk data, the free blocks for wear leveling, and bad blocks with errors. when a normal bl ock is detected broken, it is replaced with a free block and listed as a bad block. when a free block is detected broken, it is then removed from the fre e block list and marked as a bad block. during device operation, this ensure s that newly accumulated b ad blocks are transparent to the host. the device will stop file write service once there are only two fre e blocks left such that the read function is still available for copying the files from the disk into another. 5 .3 wear leveling the nand flash device s are limit ed by a certain number of write cycles. when using a fat - based file system, frequent fat table updates are required. if some area on the flash wears out faster than other s , it would significantly reduce the lifetime of the whole ssd , even if the erase counts of other s are far from the write cycle limit . thus, if the write cycle s can be distributed evenly across the media, the lif e time of the media can be prolonged significantly. th is scheme is called w ear leveling. apacer s w ear - leveling scheme is achieved both via b uffer m anagement and apacer - specific s tatic w ear leveling. they both ensure that the lifetime of the flash media can be increased, and the disk access performance is optimized as well. 5 .4 power failure management the low power detect ion on the controller initiates crucial data saving before the power supplied to the device is too low. this feature prevents the device from c rash and ensure s data integrity during a n unexpected power - off . 5 .5 ata secure erase accomplished by t he secure erase (se) command, which added to the open ansi standards that control disk drives, ata secure erase is built into the disk drive itself and thus far less susceptible to malicious software attacks than external software utilities. it is a positive easy - to - use data destroy command, amounting to electronic data shredding. e xecuting the command causes a drive to internally completely erase all possible user data. this command is carried out within disk drives, so no additional softw are is required. o nce exe cuted, neither data nor the erase counter on the device would be recoverable, which blurs the accuracy of device lifespan. the process to erase will not be stopped until finished while encountering power failure, and will be continued when power is back on .
