LOW POWER SRPG CELL

摘要

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.

主权项

1. A device including an State Retention Power Gating (SRPG) cell, the SRPG cell comprising:
at least one retention component; and at least one non-retention component, wherein the SRPG cell is operable in at least a run state, a first retention state and a second retention state, in the run state, the at least one retention component and the at least one non-retention component that are to be powered, in the first retention state, the at least one retention component is to be powered at essentially a same supply voltage as in the run state, and the at least one non-retention component is to be powered down, and in the second retention state, the at least one retention component is to be powered at a lower supply voltage than in the run state, and the at least one non-retention component is to be powered down.
