    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.

    摘要: A memory system includes a management-information restoring unit. The management-information restoring unit determines whether a short break has occurred referring to a pre-log or a post-log in a NAND memory. The management-information restoring unit determines that a short break has occurred when the pre-log or the post-log is present in the NAND memory. In that case, the management-information restoring unit determines timing of occurrence of the short break, and, after selecting a pre-log or a post-log used for restoration, performs restoration of the management information reflecting these logs on a snapshot. Thereafter, the management-information restoring unit applies recovery processing to all write-once blocks in the NAND memory, takes the snapshot again, and opens the snapshot and the logs in the past.
