Numonyx™ Flash Sector Manager (FSM)

Numonyx™ Flash Sector Manager (FSM) is a software application that resides between a FAT (or sector-based) file system and flash memory to enable Numonyx™ StrataFlash® Embedded Memory (P30/P33) and Numonyx™ StrataFlash® Cellular Memory (M).

FSM provides a small RAM/ROM footprint, consistent performance and sector-based power loss recovery. With a simple API, FSM easily enables standard FAT-based file systems to be enabled for flash support.
