Abstract: A novel nonvolatile flip-flop (NVFF) using a magnetic tunnel junction (MTJ) is presented for power gating architecture. The proposed NVFF exploits spin Hall effect (SHE) for fast and low-power data backup into MTJs before the power is gated off. Owing to the high spin injection efficiency of SHE, the estimated write current for <10-ns backup operation is lower than 40 μA. Due to the low write current requirement, we do not introduce a dedicated write driver circuit. Instead, we utilize the cross-coupled inverters in the slave latch to perform the backup operation, resulting in low area overhead. The simulation results show 10× improvement in backup energy when compared with previous works on spin transfer torque-based NVFFs. © 1980-2012 IEEE.
