ABSTRACT:
A microprocessor memory safeguard device comprising a switch having two it terminals and a common terminal. The common terminal is connected to a first terminal of the memory and to the logic zero of the microprocessor. The other input terminal of the switch is connected to one terminal of a battery. The second terminal of the memory is connected to the other terminal of the battery. The second input terminal of the switch is connected to an initialization line of the processor whose initialization input is also connected to the line. The initialization line is connected directly to a power supply source. The initialization line could also be a data bus interconnecting a plurality of microprocessors.
