Architectures and energy performance of nonvolatile SRAM (NV-SRAM) are demonstrated for nonvolatile power-gating (NVPG) that is a power-gating technique with nonvolatile state/data retention. The NV-SRAM cell consists of an ordinary 6T cell and two magnetic tunnel junctions (for nonvolatile retention) with two pass-transistors. The cell design and array architectures for leakage power reduction are developed. The SOTB CMOS technology is also introduced for the peripheral circuits to reduce the shut-down leakage. The break-even time (BET) that is an energy-performance index of NVPG is analytically formulated for arbitrary-array-size NV-SRAM with its peripheral circuits. The BET behavior with respect to the developed architectures are systematically analyzed by simulations and also using circuit parameters extracted from an implemented NV-SRAM TEG. A sufficiently short BET for the L1-cache-size NV-SRAM can be achieved, which would result in fine-grained core-level NVPG of multicore processors and SoCs. |
