Abstract
Life of a non-volatile memory is extended without increasing processing time due to turning power ON/OFF. An EEPROM stores counter information and setting information, a first RAM and a second RAM store counter information and setting information, a memory management unit manages a storage area in the first RAM for the counter information and setting information so as to be updatable and manages a storage area in the second RAM for the counter information and setting information so as not to be updatable, and a system control unit, when a change in contents of the counter information and the setting information occurs, rewrites the counter information and the setting information in the first RAM in accordance to the changed contents, and when the power is turned OFF, reads and compares the counter information and the setting information in the first RAM with the counter information and the setting information in the second RAM, and writes only different data to the EEPROM.
