Abstract An information processing apparatus including a NAND type flash memory; circuitry configured to control writing/reading of data to/from the NAND type flash memory; and an interface configured to connect the information processing apparatus to a host apparatus. The circuitry is configured to determine whether to erase data stored in a specific area within the NAND type flash memory by overwriting the data based on whether an overwrite command is received from the host apparatus via the interface; and erase a physical block including the specific area when it is determined to erase the data by removing electric charges in the NAND type flash memory in the physical block including the specific area.
