Abstract:
A memory device structure includes a wafer substrate and a magnetic tunnel junction (MTJ) positioned above an upper surface of the wafer substrate. The MTJ includes a first magnetic layer, a second magnetic layer laterally adjacent the first magnetic layer, and a nonmagnetic layer interposed between the first and second magnetic layers, wherein the first magnetic layer, the nonmagnetic layer and the second magnetic layer comprise a substantially vertical layer stack that extends along a first direction that is substantially perpendicular to the upper surface of the wafer substrate. A first contact is electrically coupled to the first magnetic layer and a second contact is electrically coupled to the second magnetic layer.
