Abstract:
A memory cell comprising:a first conductor having a first width;a second conductor having a second width;a steering element for providing enhanced current flow in one direction through the steering element having a first end surface with first opposite edges spaced-apart by a distance equal to the first width and second opposite edges spaced-apart by a distance equal to the second width where the first opposite edges are aligned with the first conductor and where the first end surface is in continuous contact with the first conductor;a state change element for retaining a programmed state, connected in series with the steering element having a second end surface with third opposite edges spaced-apart by a distance equal to the first width and fourth opposite edges spaced-apart by a distance equal to the second width where the fourth opposite edges are aligned with the second conductor and where the second end surface is in continuous contact with the second conductor, and;the steering element and state change element being vertically aligned with one another.
