PROBLEM TO BE SOLVED: To provide a flash memory system with high access efficiency to flash memory. SOLUTION: The memory controller for controlling access to a flash memory 11 comprises address registers 23a and 23b for retaining physical addresses on the flash memory 11. In accessing to the flash memory 11, address data based on a physical address retained in the address register 23a is given to the flash memory 11, and a physical address for next access to the flash memory 1 is set in the address register 23b. After the physical address retained in the address register 23a is given to the flash memory 11, the physical address retained in the address register 23b is transferred to the address register 23a and retained therein.
