Abstract
One embodiment provides a method for reducing leakage current in device logic having an operational supply-voltage threshold, a nonzero data-retention supply-voltage threshold, and two or more on-die transistor switches to switchably connect a voltage source to the device logic. After the logic enters an idle period, one or more of the switches are opened to lower a supply voltage of the logic below the operational supply-voltage threshold but above the data-retention supply-voltage threshold. When the logic exits the idle period, one or more of the switches are closed to raise the supply voltage of the logic above the operational supply-voltage threshold.
