According to the present invention, there is provided an information storage apparatus having a non-volatile memory device in which a data erase block is larger than a data write block, the apparatus comprising erase means for effecting erase in the non-volatile memory device on the basis of a write command from a host, a clean block pointer that stores an address of an erase area in the non-volatile memory device, which is erased by the erase means, and information indicative of a position of a write block in the erase area, up to which data is written, determination means for determining, based on the clean block pointer, whether data associated with the write command is writable in the erase area in the non-volatile memory device, which is erased by the erase means, and write means for writing the data associated with the write command in the erase area, when the determination means determined that the data is writable.
