This paper presents a comparative study of leakage reduction techniques applied to a 90 nm 6T SRAM to find an optimal design for ultra-low power wireless sensor applications. A 4-Kb SRAM implemented with the proposed techniques has a leakage as low as 26.5 nA in the idle mode, a 189? improvement over a memory without applying such techniques
