Abstract
A device structure includes first electrically conductive lines, second electrically conductive lines that are vertically spaced apart from the first electrically conductive lines, a two-dimensional array of magnetic tunnel junctions located between the first electrically conductive lines and the second electrically conductive lines, and a two-dimensional array of selector elements located in series with the two-dimensional array of magnetic tunnel junctions. Each of the magnetic tunnel junctions includes a respective reference layer, a respective nonmagnetic tunnel barrier layer, and a respective free layer, and has a respective pair of first tapered planar sidewalls laterally extending along a first horizontal direction and a respective pair of second tapered planar sidewalls laterally extending along a second horizontal direction.
