This apparatus comprises a battery ( ) for supplying a voltage to the apparatus, a power cut detecting circuit ( ) for detecting cuts of this supply voltage, a random-access memory ( ) fed by this battery ( ). A processor ( ) loads this data memory. To avoid this memory being reloaded after a very brief electric power cut of the battery, its integrity is tested. If its contents have remained intact, there is no need for it to be reloaded.

Method for restarting an apparatus if the integrity of data in a memory is lost during micro-outage of power supply

This apparatus includes a detector (60) for detecting a change of accumulator (21). Thus a counter (DECH) measuring the charge state of this accumulator may be re-initialized if the accumulator is charged even during a period of inactivity of the apparatus.
