    摘要: To provide a memory system that can surely restore management information even when a program error occurs during data writing. After “log writing (1)” for a pre-log, when a program error occurs when data writing is being performed (a data writing error), the memory system performs the data writing again without acquiring a pre-log corresponding to data rewriting processing. After finishing the data writing, the memory system acquires, without generating a post-log, a snapshot instead of the post-log and finishes the processing.

    摘要: A memory system includes a DRAM 20 that performs writing and readout in a unit equal to or smaller than a cluster, a NAND memory 10 that performs writing and readout in a page unit, and a management table group in which management information including storage locations of data stored in the DRAM 20 and the NAND memory 10 is stored. When a readout request is received from the outside, a data managing unit 120 notifies, when an unwritten logical address area is present in a storage area of the NAND memory to which a logical address area requested to be read out is mapped, fixed data stored in the DRAM 20 to the outside in association with the logical address area.

    摘要: A memory system includes a controller that manages data stored in the first and second storing areas. The controller determines, when a readout error occurs when the stored data in the second storing area is read out, success or failure of error correction to the read-out data based on the result of the error correction stored in a storage buffer, writes, when the error correction is successful, correction data corresponding to the read-out data stored in the storage buffer, and writes, when the error correction fails, the read-out data itself not subjected to error correction processing.
