Information processing device that extends service life of non-volatile semiconductor memory and recording medium

Abstract

An information processing device includes a volatile memory, a non-volatile semiconductor memory, a storage circuit, and a processor. The processor records corresponding update information in a first log area when updating actual data in a first actual data area by the update data. The processor collects the update information recorded in the first log area at a specific timing. The processor writes the collected update information to a second log area. After writing the collected update information, the processor initializes the first log area. When the second log area becomes full, the processor writes the actual data in the first actual data area to the corresponding second actual data area. After writing the actual data, the processor initializes the first log area and the second log area.
