摘要：It is possible to prevent unoccupied blocks from being depleted by a write oflogical-physical management information. A processor is capable of performing anunoccupied user block generation process by moving user data stored in allocated userblocks in order to generate unoccupied user blocks serving as unoccupied blocks amongallocated user blocks, and performing an unoccupied meta block generation process bymoving meta data stored in allocated meta blocks in order to generate unoccupied metablocks serving as unoccupied blocks among the allocated meta blocks. The processorcalculates the number of unoccupied meta blocks to be consumed, that is, the number ofunoccupied meta blocks to be consumed by the unoccupied user block generationprocess. The processor performs the unoccupied meta block generation process basedon the number of unoccupied meta blocks to be consumed.
