Researchers from Holst Centre, imec and and the Katholieke Universiteit Leuven (K.U. Leuven) have demonstrated the world’s most energy efficient 64kbit SRAM operating at 90MHz. At just 2.65pJ per access, the new SRAM consumes 5-20 times less energy than the previous state of the art. It opens the door to a range of new energy-harvesting applications in body-area networks (BANs) for healthcare and sensor networks for smart buildings. BANs promise heath monitoring systems that can keep an eye o...
