The application issues an access request of a memory device to the dedicated file system. The dedicated file system performs an access control to the memory device. The dedicated file system manages a logical address space of the memory device in each predetermined unit area, and sequentially writes data to any of unused unit areas that are reserved. The sequential writing to the unit areas is constituted of one or a plurality of write instructions. The application issues the access request to the dedicated file system without recognizing a unit area size. |
