ABSTRACT:
A programmable resistance memory element. The active volume of memory material is made small by the presence of a small area of contact between the conductive material and the memory material. The area of contact is created by forming a region of conductive material and an intersecting sidewall layer of the memory material. The region of conductive material is preferably a sidewall layer of conductive material.
