Abstract
A method of forming a memory device includes forming vertical stacks each including a respective first electrically conductive line and a respective selector rail over a substrate, such that the vertical stacks laterally extend along a first horizontal direction and are laterally spaced apart from each other along a second horizontal direction, forming magnetic tunnel junction material layers over the vertical stacks, and patterning the magnetic tunnel junction material layers and an upper portion of each of the selector rails to form a two-dimensional array of magnetic tunnel junctions and periodic notches at least in an upper portion of each of the selector rails.
