A method, and a system of using the method, of preserving memory of a processor powered by an external source. The method includes determining a drop in a first power to be supplied to the processor, generating a reset signal when the drop falls below a threshold, supplying a second power from a power store to the processor based on the reset signal, and holding the reset signal until the first power rises above the threshold.

What is claimed is: 1. A method of preserving memory of a processor configured to be powered by an external source, the method comprising:determining a drop in a first power to be supplied to the processor;generating a first intermediate reset signal when the first power falls below a threshold;supplying a second power from a store to the processor based on the first intermediate reset signal;deriving a reference signal from the second power;comparing the reference signal with the first power;generating a second intermediate reset signal when the reference signal is greater than the first power;activating a reset circuit with at least one of the first intermediate reset signal and the second intermediate reset signal; andoutputting a processor reset signal from the reset circuit.
