Abstract :
SRAMs capable of operating at extremely low supply voltages-for example, below the transistor threshold voltage-can enable ultra-low-power battery-operated systems by allowing the logic and memory to operate at the same optimal supply voltage. This review article presents SRAM techniques including new bit cells, novel sensing schemes, and read/write assist circuits for ultra-low-power applications.
