Abstract
User data transferred from a host apparatus and a first information tableindicating correspondence between a logical address and a physical address are recorded in a first region of a flash memory. A second information tablecomposed of the physical block address storing the first information tableand the number of times of update of the physical block for recording the first information table from the time of manufacturing is recorded in a second region of the flash memory. The physical blocks of the first and the second regions are recorded independently from each other in a rotational manner. According to the recording of the second information table, the total number of times of rewriting of the first region is converted. This can suppress the number of times of rewriting of the second region and improve reliability of the number of times of update of the first information table from the time of manufacturing, the number being recorded in the second region.
