<P>PROBLEM TO BE SOLVED: To provide a memory system for surely restoring management information even when any program error occurs during data write-in. <P>SOLUTION: When any program error occurs during data write-in (data write-in error) after the "log write-in (1)" of a pre-log, the pre-log corresponding to data rewrite processing is not acquired, but data write-in is performed again. Then, after the end of the data write-in, a post-log is not acquired, but a snapshot is acquired instead, and the processing is ended. <P>COPYRIGHT: (C)2009,JPO&INPIT |
