Abstract

An integrated circuit includes a vertical diode, a first electrode coupled to the vertical diode, and a resistivity changing material coupled to the first electrode. The integrated circuit includes a second electrode coupled to the resistivity changing material and a spacer having a first sidewall contacting a first sidewall of the first electrode and a sidewall of the resistivity changing material.
