    摘要: A memory system includes a volatile first storing unit, a nonvolatile second storing unit, and a controller. The controller performs data transfer, stores management information including a storage position of the data stored in the second storing unit into the first storing unit, and performs data management while updating the management information. The second storing unit has a management information storage area for storing management information storage information including management information in a latest state and a storage position of the management information. The storage position information is read by the controller during a startup operation of the memory system and includes a second pointer indicating a storage position of management information in a latest state in the management information storage area and a first pointer indicating a storage position of the second pointer. The first pointer is stored in a fixed area in the second storing unit and the second pointer is stored in an area excluding the fixed area in the second storing unit.

    摘要: A memory system (11) includes a nonvolatile memory (10) including a plurality of blocks as data erase units, a measuring unit (31) which measures an erase time at which data in each block is erased, a block controller (30) having a block table which associates a state value indicating one of a free state and a used state with the erase time for each block, a detector which detects blocks in which rewrite has collectively occurred within a short period, a first selector (32) which selects a free block having an old erase time as a first block, on the basis of an information in the block table, a second selector (33) which selects a block in use having an old erase time as a second block, on the basis of the information in the block table, and a leveling unit (35) which moves data in the second block to the first block if the first block is included in the blocks detected by the detector.
