Abstract: A spin-orbit torque magnetoresistive random access memory and a method of operating the same. The memory includes memory cells. Each memory cell includes: an orbital Hall layer for generating an orbital polarized current under an action of an in-plane current; an alloy material layer including an alloy material having spin Hall angles with opposite polarities and for generating spin polarized currents in opposite spin directions under an action of the in-plane current flowing through the alloy material layer and the orbital polarized current; a magnetic tunnel junction, including a magnetic free layer, a tunneling insulation layer, a magnetic pinned layer, and an antiferromagnetic layer or artificial antiferromagnetic layer. A competing spin current effect is generated by the spin polarized currents in the opposite spin directions to induce a deterministic magnetization switching of a magnetic moment of the magnetic free layer, so as to store an information in the memory cell.
