This apparatus comprises a battery (15) for supplying a voltage to the apparatus, a power cut detecting circuit (20) for detecting cuts of this supply voltage, a random-access memory (12) fed by this battery (15). A processor (10) 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.
