Abstract
According to one embodiment, when being notified of an interruption of an external electric power supply, a second processor performs a saving operation for storing management information and data stored in a first volatile memory to a first non-volatile memory, and records a progress log, indicating a progress of the saving operation, into a second volatile memory. The first processor periodically checks whether the progress log is recorded in the second volatile memory or not, and when the progress log is recorded in the second volatile memory, the first processor stores the progress log into the second non-volatile memory.
