The most efficient power saving method in digital systems is to scale Vdd, owing to the quadratic dependence of dynamic power consumption. This requires memory working under a wide range of Vdds in terms of performance and power saving requirements. A self-timed 6T SRAM was previously proposed, which adapts to the variable Vdd automatically. However due to leakage, the size of memory is restricted by process variations. This paper reports a new self-timed 10T SRAM cell with bit line keepers developed to improve robustness in order to work in a wide range of Vdds down to 0.3V under PVT variations. In addition, this paper briefly discusses the potential benefits of the self-timed SRAM for designing highly reliable systems and detecting the data retention voltage (DRV).
