Abstract

A magneto-resistive memory cell and a method of forming the memory cell, includes a substrate, a single crystalline semiconductor diode formed in the substrate; and a first thin film conductor recessed in the substrate, and a second thin film conductor form above a magnetic tunnel junction formed on the diode. The diode and first thin film conductor share a non-planar common surface, such that the metal tunnel junction is a predetermined distance from the thin film conductor.
