Abstract:
1. A method of providing power to a volatile circuit when its primary power source is inactivated, comprising: providing a first power signal from the primary power source to the circuit to maintain volatile states of the circuit during a first mode of operation; terminating the first power signal to the circuit in preparation of transferring to a second mode of operation; providing a second power signal having a different power value from the first signal to the circuit substantially concurrently with the inactivation of the first power signal to commence the second mode of operation; inactivating the second power signal to the circuit in preparation of returning to the first mode of operation; and providing the first power signal to the circuit substantially concurrently with the inactivation of the second power signal during the return to the first mode of operation.
