<p>PURPOSE: To reduce the consumption of battery power by a ROM. CONSTITUTION: The power supply from a battery 4 to the ROM 2 is cut off by turning OFF a switch 5 when a processing program stored on the ROM 2 can be executed on a RAM 3. The power consumption of the battery 4 by the ROM 2 can be suppressed, so the frequency of the charging, replacement, etc., of the battery 4 is reduced. The memory to which the power supply is cut off is the ROM 2, so the processing program on the ROM 2 is never destroyed even if the power supply is cut off.</p> |
