A NAND controller (6a) determines a range for retrieving a physical page that will serve as a data writing destination, in accordance with a logical address of the data that is to be written to a NAND devices (7a-7h) having a plurality of physical pages. From among the physical pages included in the determined range, the NAND controller (6a) retrieves a physical page to which data has not been written. Next, the NAND controller (6a) writes the data to the retrieved physical page to which data has not been written. |
