    摘要: A storage medium reproducing apparatus includes a storage unit, a correction history storage unit, a correction history implementing unit, and a correcting unit. The storage unit includes a plurality of information storage units storing information depending on whether a charge quantity is greater than a predetermined charge quantity threshold value, and a correction code storage unit storing error correction codes for the information stored in the information storage units. The correction history storage unit stores a correction history containing identification information for the information storage unit corrected with an error correction code is performed, and a content of the correction. The correction history implementing unit corrects information in compliance with the content of the correction when the information is read from the information storage unit. The correcting unit performs a correcting operation using an error correction code on the corrected information, and registers the correction history of the corrected information storage unit.

    摘要: According to one embodiment, a controller controls writing into and reading from a storage apparatus that includes a first data-storage unit and a second data-storage unit. The second data-storage unit stores user data and parity data of the user data. The first data-storage unit stores the parity data. The controller includes a parity updating unit and a parity writing unit. When parity data is updated, the parity updating unit writes the updated parity data into the first data-storage unit. When a certain requirement is satisfied, the parity writing unit reads the parity data written in the first data-storage unit, and writes the parity data thus read into the second data-storage unit.

    摘要: When data in one semiconductor memory device is corrupted during a padding process by a padding unit and the data cannot be recovered even by using an error correcting code for correcting a data error, a storage control device issues a data recovery request to a data recovery device. The data recovery device reads the data from other semiconductor memory device in response to the data recovery request to recover the data, and returns a recovery result to the padding unit in the storage control device to perform the padding process.

    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.
