Semiconductor memory device that stores a rewrite frequency of a nonvolatile memory included in the semiconductor memory device
A semiconductor memory device that stores information includes: a flash memory that is managed by a predetermined file system having a parameter dependent on the semiconductor memory device; a rewrite frequency storage unit that stores a rewrite frequency of the flash memory; an ID detection unit that detects whether or not first identification information associated with the rewrite frequency is stored in the flash memory as the parameter; and a control unit that, when the ID detection unit detects that the first identification information is stored, reflects the rewrite frequency stored in the rewrite frequency storage unit, on a storage area corresponding to the first identification information.
