Abstract:
A method is for recovering a block mapping table in a system including a flash memory device, where the block mapping table utilizes address mapping in accordance with a wear-leveling scheme. The method includes reading block arrangement information from the flash memory device for the wear-leveling scheme, restoring the block mapping table with reference to allocation block information included in the block arrangement information and scanning address allocation information included in spare regions of erased blocks of the flash memory device with reference to erased block information included in the block arrangement information and updating the block mapping table in accordance with the scanned address allocation information.
