Abstract
A low power State Retention Power Gating (SRPG) cell has a retention component and a non-retention component, and is operable in a run state, a first retention state, and a second retention state. In the run state, the retention and non-retention components are powered with a supply voltage. In the first retention state, the retention component is powered at the same supply voltage as in the run state, and the non-retention component is powered down. In the second retention state, the retention component is powered at a lower supply voltage than in the run state, and the non-retention component is powered down.
