Abstract
Disclosed herein are a flash file system and an address translation method. The flash file system includes a file system, a Flash Translation Layer (FTL), and flash memory. The FTL receives Local Block Addresses (LBAs) from the file system, and translates the LBAs into Physical Block Address (PBAs. The flash memory receives the resulting PBAs. The FTL includes a memory block in which a multi-stage clustered hash table for mapping the LBAs to the PBAs is stored, and performs the address translation using the clustered hash table.
