Medical diagnosis and healthcare are at the onset of a revolution fueled by improvements in smart sensors and body area networks. Those sensor nodes' computation and memory requirements are growing, but their energy resources do not increase; thus, more energy-efficient memories and processors are required. New circuit-design techniques that drastically reduce the static RAM (SRAM) memories' energy consumption while still achieving tens of megahertz of operation are discussed.
