This paper describes back-gate biasing scheme using independent-gate controlled asymmetrical (n+/p+ polysilicon gates) FinFETs devices and its applications to 6-T and 8-T SRAM. Row-based above-VDD/below- GND bias is applied to the back-gates of the access and pull-down cell nFETs to enhance the Read/Write performance, reduce standby leakage, and mitigate process (VT) variability. The application of the technique to stacked Read transistors in 8-T SRAM is also discussed.
