摘要：
A method includes providing power to on-die combinatorial circuitry of an integrated circuit (IC) from an external power supply regulator during an active mode of the IC. A state of the on-die combinatorial circuitry of the IC is moved into on-die storage of the IC. Power to the on-die combinational circuitry is disabled during a low power mode of the IC by disrupting power supplied from the external power supply regulator to the IC. A power feedback signal from an internal portion of the IC is provided to the external power supply regulator.
