ABSTRACT:
According to exemplary embodiments, 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 includes an erase device to effect 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, and information indicative of a position of a write block in the erase area, up to which data is written, a determination device to determine, 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 device, and a write device to write the data associated with the write command in the erase area, when the determination device determined that the data is writable.
