    摘要： A memory system includes a nonvolatile memory including blocks as data erase units, a measuring unit which measures an erase time at which data in each block is erased, a block controller 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 which selects a free block having an old erase time as a first block, a second selector which selects a block in use having an old erase time as a second block, and a leveling unit which moves data in the second block to the first block if the first block is included in the blocks detected by the detector.

    摘要： According to one embodiment, a disk array control device manages a plurality of drives as a single logical drive. The disk array control device includes a first register configured to store a to-be-accessed drive number which is designated by a host, and a control module. The control module is configured to receive a command from the host, determine whether the received command is a predetermined command which is used for maintenance of each of the drives, and execute, in a case where the received command is the predetermined command, a pass-through process of sending the received command to the drive which is designated by the to-be-accessed drive number in the first register.
