With transistors getting smaller and smaller by every year, power dissipation has become a major issue. Flip-Flops are one of the most common and highly used units in electronics, and it is one of the many units that faces problems with down-scaling of the transistors. To face these problems engineers have tried to come up with solutions such as turning off the circuits in certain times to reduce the power dissipation. But this operation has the issue of losing the stored data in the circuit. To overcome this issue, designers have been using the MTJ devices in order to make the circuits non-volatile. She assisted MTJ devices due to their better speed and lower power consumption are favored compared to other MTJ devices. In this paper we introduce a non-volatile Flip-Flop that provides up to 54%, 5% and 17% improvements in write energy, clk-q delay and power-delay-product respectively in comparison to the other circuits that have been compared.
