  • Patent number: 11374164
    Abstract: Embodiments herein relate to a system, apparatus, and/or process for producing a spin orbit torque (SOT) electrode that includes a first layer with a first side to couple with a free layer of a magnetic tunnel junction (MTJ) and a second layer coupled with a second side of the first layer opposite the first side, where a value of an electrical resistance in the first SOT layer is lower than a value of an electrical resistance in the second SOT layer and where a current applied to the SOT electrode is to cause current to preferentially flow in the first SOT layer to cause a magnetic polarization of the free layer to change directions. During production of the SOT electrode, the second layer may act as an etch stop.
