Claim Text:
1. A magnetic memory device, comprising: a magnetoresistive element including a free layer, a pinned layer, and a separation layer between the free layer and the pinned layer; a first conductive line contacting the free layer and configured to apply a Rashba field to the free layer; and a second conductive line spaced apart from the free layer and configured to apply an external magnetic field to the free layer, wherein the magnetic memory device is configured to apply a first current to the first conductive line to induce the Rashba field, the Rashba field being applied to the free layer in a first direction parallel to the free layer, wherein at least a portion of the external magnetic field is applied to the free layer in a second direction perpendicular to the first direction and parallel to the free layer, and wherein a magnetization direction of the free layer is switchable in a vertical direction by application of the Rashba field and the external magnetic field to the free layer.
