Abstract
A data storage temporarily stores an address conversion table associating the sector numbers with the physical addresses for each file. A conversion table memory allocator allocates a memory region for the address conversion table corresponding to a file when a request is made to open the file. A file system manager releases the allocated memory region at a given time. The file system manager stores sector numbers of one or multiple sectors constituting a file in each record of the address conversion table for which the memory region is allocated in sequence. Then, a memory control section searches the flash memory to acquire a physical address corresponding to a sector number in the each record of the address conversion table, and stores each acquired physical address in the corresponding record.
