Abstract
Spin-orbit torque magnetic tunnel junction (MTJ) based non-volatile flip-flops (NVFFs) have been introduced to provide zero-leakage standby state without data loss in power-gating mode. In this Letter, the data-aware backup scheme for NVFF, where significant energy can be saved by performing data backup only when the stored data and the current data are different is proprosed. Low-area backup signal generator is also proposed for the proposed data backup scheme. The simulation results with 65 nm process show 88.7% reduction in backup energy when the stored data and the current data are equal.
