Abstract

Embodiments of the present invention provide systems and methods for reducing power consumption during the operation of a SRAM cell. Embodiments of the present invention reduce power consumption by determining switching activity, and based off a determination of low switching activity, gates off a core which is not written; and limits switching activity on the unaddressed core by applying the highest order bit.
