Abstract:

Aiming at the limitations of the Flash file system of the NAND Flash Transition Layer(NFTL) on Largescale Nand Flash Memory, the paper analyses the storage mechanism of NFTL, presents an improved algorithm and gives an implementation procedure in detail based on the vxworks embedded system platform. The result shows that the new NFTL  greatly increases the the speed of read/write operation and shortens the mount time.
