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

A non-transitory computer-readable recording medium storing an information processing program for controlling an information processing device, the information processing program causing the information processing device to operate as:

• a volatile memory that includes a first actual data area and a first log area, the first actual data area recording actual data, the first log area recording update information including update data, the update data being for updating the actual data recorded in the first actual data area;
• a non-volatile semiconductor memory that includes a plurality of blocks and a second actual data area, at writing of the actual data, the non-volatile semiconductor memory being initialized in units of the blocks, the second actual data area recording the actual data in units of the blocks;
• a storage circuit that includes a second log area to which the update information recorded in the first log area is wrote;
• and
• a processor that (i) records corresponding update information in the first log area when updating the actual data in the first actual data area by the update data, (ii) collects the update information recorded in the first log area at a specific timing, (iii) writes the collected update information to the second log area, (iv) after writing the collected update information, initializes the first log area, (v) when the second log area becomes full, writes the actual data in the first actual data area to the corresponding second actual data area, (vi) after writing the actual data, initializes the first log area and the second log area.
