In this paper, we present the first deep sub-threshold 6-T SRAM which functions from 1.2V to 193mV, fabricated in an industrial 0.13?m CMOS technology. It provides 1.6x energy efficiency improvement over the previously proposed mux-based, sub-threshold SRAM designs while using only half the area. Adjustable footer and headers are introduced, as well as body bias techniques to allow low-voltage operation.
