Whimory is the name of the Flash Translation Layer (FTL) used in several NAND-flash based mp3 players.

FTLs typically manage the following tasks:

• Presenting the flash as a simple block-device to the filesystem layer above
• Wear leveling of the NAND flash, spreading out the erase operations evenly over all blocks
• Error detection and correcting
• Bad-block management, keeping a list of bad flash blocks so they are no longer used to store data

Players using the Whimory FTL include:
