Power gating (Vdd gating)

Tag: power-gating

Aliases: Vdd-gating, Vdd gating, power-gating

A static-power-saving technique that cuts the Vdd or ground connection to a circuit block via a header/footer transistor, eliminating leakage entirely. Loses any state stored in the block and incurs a wakeup latency to re-establish supply voltage.
