Numonyx™ NAND Flash Translation Layer (NFTL)



Numonyx™ NFTL is a software sector manager that resides between a FAT (or sector-based) file system and flash memory to enable Numonyx NAND flash memory.

Numonyx NFTL provides a small RAM/ROM footprint, consistent performance and sector-based power loss recovery. Numonyx NFTL is designed to work with Numonyx SCFS but with its simple API, Numonyx NFTL easily enables standard FAT-based file systems for flash support.
