As technology advances, SRAM core voltage reduction has lagged behind logic voltage, and has become a limiting bottleneck for semiconductor chip power consumption improvement. The main limiting factor is that the minimum voltage (Vmin) of an SRAM write voltage cannot be scaled down aggressively due to increased threshold voltage variations and increased SRAM capacity requirements as the device size decreases. To resolve this issue, write assist circuits have become a main focus of interest to allow further reduction of the minimum voltage (Vmin) without write failure. Write failure usually occurs when a pass gate transistor cannot overpower a corresponding pull up transistor in an SRAM cell. Improvements in this area would be beneficial to the art.
