  • Abstract
    This design sets a record low energy consumption (average RD/WR) of 2.65pJ/access for a 64kbit embedded SRAM operating at 90MHz in 65nm LP CMOS. This low energy and variability resilient SRAM macro ensures write-ability with an innovative Mimicked Negative Bit-line technique. The novel low energy Charge Limited Sequential sense amplifier consumes 11.36fJ/decision and obtains σVoffset of 14.297mV without requiring calibration.
