ABSTRACT:
A storage apparatus using a nonvolatile memory as a cache and a mapping information recovering method for the storage apparatus are provided. The storage apparatus includes a mapping information storage module which stores in the nonvolatile memory mapping information of the nonvolatile memory and a first physical block address allocated when the mapping information is stored; a scan module which scans the first physical block address through a second physical block address allocated currently; and a mapping information recovery module which recovers the mapping information between the first physical block address and the second physical block address based on a result of the scan by the scan module.
