映射表数据恢复方法及装置

Abstract

The invention discloses a mapping table data recovery method and a device. The mapping table data recovery method is applied to a nonvolatile memory, the nonvolatile memory comprises at least one memory area, and the mapping table data recovery method comprises the following steps: establishing a mapping table corresponding to the memory area, and saving to the distributed memory space in the memory area; establishing memory address records of the mapping table and saving according to the tag of the memory area; after operating the memory area, obtaining an identifier of the memory area for saving; and extracting the corresponding mapping table according to the identifier of the memory area, and carrying out mapping table data recovery. The mapping table data recovery device improves the speed of data recovery and the reliability of a whole flash memory system.
