ABSTRACT:
An electrical circuit contains volatile states that are lost without continued application of power to circuit elements to preserve their volatile states. A first power source in the circuit provides power to the volatile state circuit for holding and preserving their volatile states. A power selection circuit is coupled to the circuit elements and has a plurality of selectable modes. A first mode of operation of the power selection circuit is selected when the circuit elements are to be operated at a first power level via the first power source which constitutes a first mode of operation. A second mode of operation is selected when the volatile state circuit elements are to be operated under a condition where the first power source is inactivated, such as, for example, during a circuit backup or standby operation. During the second mode of operation, the circuit elements volatile states are preserved via a power selection circuit that provides power from a second power source at a second power level, different from the first power level, to the volatile state circuit elements in place of the first power source.
