A low‐power fast‐switching write‐and‐standby shared assist circuit for low‐voltage SRAMs

Abstract

Assist circuitry helps the SRAM to lower the supply voltage VDD to reduce power consumption. Separately designed read, write, and standby assists for low voltage (LV) are not area- and power-efficient. This paper proposes a fast-switching VDD-lowering circuit without inducing direct current to achieve a single low-power write-and-standby shared assist circuit. Experimental results verify that the proposed assist can achieve significant power reduction no matter in the write or the standby modes.
