Reliability

Wear-Leveling algorithm

The controller supports static/dynamic wear leveling. When the host writes data, the controller will find and use the block

with the lowest erase count among the free blocks. This is known as dynamic wear leveling. When the free blocks' erase

count is higher than the data blocks', it will activate the static wear leveling, replacing the not so frequently used user

blocks with the high erase count free blocks.

ECC algorithm

The controller uses BCH8/BCH15 ECC algorithm per 512 bytes. BCH8/BCH15 can correct up to 8 or 15 random error

bits within 512 data bytes.

Bad-block management

When the flash encounters ECC failed, program fail or erase fail, the controller will mark the block as bad block to

prevent the used of this block and caused data lost later on.
