Abstract:
1. A magnetic tunnel junction (MTJ) device comprising: a substrate including a trench; a conductive terminal disposed within the trench, wherein the conductive terminal comprises: a magnetic tunnel junction (MTJ) structure disposed within the trench, the MTJ structure including a fixed magnetic layer having a fixed magnetic orientation, a tunnel junction layer, and a free magnetic layer having a configurable magnetic orientation, the fixed magnetic layer coupled to the conductive terminal along an interface that extends substantially normal to a surface of the substrate, the free magnetic layer proximate to the conductive terminal to carry a magnetic domain configured to represent a digital value, wherein the fixed magnetic layer includes a first portion coupled to the first conductive terminal via the anti-ferromagnetic layer along a first interface that extends substantially normal to a surface of the substrate, wherein the fixed magnetic layer includes a second portion coupled to the second conductive terminal via the anti-ferromagnetic layer along a second interface that extends substantially normal to the surface of the substrate, and wherein the fixed magnetic layer includes a bottom portion that extends substantially parallel to the surface of the substrate.
