Abstract: The present invention enables fast transition between sleep and normal modes for circuits such as digital circuits. This invention utilizes chip internal charge transfer operations to put the circuit into fast sleep. The invention reduces external power involvement, and it expedites the sleep mode transition time by limiting charge transfers within the circuit. The fast sleep and fast wake-up enable more efficient power management of the system. This functionality also maximizes performance per power, and provides a more energy efficient computing architecture.
