Claim Text:
1. A three-phase non-volatile flip-flop (NVFF) comprising: a master stage comprising a dual giant spin Hall effect (GSHE)-magnetic tunnel junction (MTJ) structure, the dual GSHE-MTJ structure comprising a first GSHE-MTJ and a second GSHE-MTJ coupled between a first combined terminal and a second combined terminal; a first pass gate transistor directly connected to a first read terminal of the first GSHE-MTJ and a second pass gate transistor directly connected to a second read terminal of the second GSHE-MTJ; and a slave stage coupled to the master stage through the first pass gate transistor and the second pass gate transistor, the slave stage comprising a first inverter cross-coupled with a second inverter, wherein the slave stage is configured to be initialized during an initialization phase of a first clock cycle of a clock, based on a first control signal; and wherein a first data value stored in the master stage is configured to be read out from the master stage and transferred to the slave stage based on a second control signal applied to a gate of the first pass gate transistor and a gate of the second pass gate transistor, and provided as an output of the three-phase NVFF, during a read phase of the first clock cycle; and a second data value provided as an input to the three-phase NVFF is configured to be written to the master stage based on a third control signal during a write phase of the first clock cycle.
