Abstract
A magnetic tunnel junction (MTJ) element includes a free layer, a pinned layer on the free layer, and a dielectric layer extending between the free layer and the pinned layer. A spin orbit torque (SOT) generator is provided, which contacts at least a portion of the free layer. A plane extending between the SOT generator and the free layer intersects a plane extending between the free layer and the dielectric layer. The SOT generator is configured to modulate current that passes between the free layer, the dielectric layer, and the pinned layer. This SOT generator can include a pair of electrodes that are spaced apart from each other in a direction orthogonal to a stacking direction of the free layer, the dielectric layer and the pinned layer. This SOT generator may include a metal selected from a group consisting of Pt, W, and Ta, or may include a topological insulator.
