Power gating circuitry and methods

Abstract

In one implementation, a circuit for power-switching includes: power gating circuitry and a first back metal, where a single output of the power gating circuitry is configured to provide at least one of power and ground supply by way of the first back metal to a word line driver circuitry. A method for power-switching includes: providing a power gating circuitry and one or more back metals; and providing, by the power gating circuitry, at least one of power and ground supply through the one or more back metals to a word line driver circuitry. A method of fabrication includes: fabricating a memory macro unit; forming one or more back metals; and coupling power gating circuitry and word line driver circuitry of the memory macro unit by way of the one or more back metals.
