Abstract:
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.

Claim (Index 25):
A method of controlling a memory system comprising:\n managing data stored in a nonvolatile memory based on part of first management information in a volatile memory, the first management information relating to correspondence between address information of the data and address information of the nonvolatile memory; storing a log and the first management information into the nonvolatile memory as second management information, the log being updated according to an execution of a data writing processing, and in responding to an occurring shutdown of power supplying from outside of the memory system, storing the first management information in the volatile memory into the nonvolatile memory as third management information.
