<P>PROBLEM TO BE SOLVED: To provide a memory system for detecting an incorrect power-off easily and reliably. <P>SOLUTION: An Active log indicating that a system is running is recorded in a NAND log 203 before a first difference log is recorded in the NAND log 203 after system startup, and a Standby log indicating that the system halts is recorded in the NAND log 203 following the difference log at normal system halt, and it is judged whether normal system halt has been performed or incorrect power-off has been performed last time based on the recorded state of the Active and Standby logs in the NAND log 203 at system startup. <P>COPYRIGHT: (C)2010,JPO&INPIT |
