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.
