Abstract:
1. A semiconductor memory device that stores information, said semiconductor memory device comprising: a nonvolatile memory that is managed by a predetermined file system which manages a parameter dependent on said semiconductor memory device, the parameter including a first storage area and a second storage area, wherein said semiconductor memory device is configured to store a rewrite frequency of said nonvolatile memory, wherein said semiconductor memory device is configured to detect whether or not first identification information is stored in the first storage area of the parameter, the first identification information being a rewrite frequency identifier indicating that the rewrite frequency of said nonvolatile memory is stored in said semiconductor memory device, and wherein said semiconductor memory device is configured to, when said semiconductor memory device detects that the first identification information is stored, reflect the rewrite frequency stored in said semiconductor memory device on the second storage area of the parameter corresponding to the first identification information.
