PROBLEM TO BE SOLVED: To prevent the exchange/alteration of a ROM of a memory module. SOLUTION: Backup power 2b is supplied to an RTC 2c-1 provided in a processing part 2 through the memory module 3 (wiring 3c) and the supply of the backup power is eliminated in the case that the memory module is detached from the processing part. The backup power 2b is supplied to a RAM 2c-2 without interposing the memory module 3. By confirming whether or not there is the decline of a power supply voltage for the RTC 2c-1 and the RAM 2c-2 at the time of power supply, whether or not the memory module is detached from the processing part is detected. Fraudulent actions are suppressed by reporting an error or stopping a game when it is judged that the memory module is detached. COPYRIGHT: (C)2006,JPO&NCIPI
