Claim:
1. A non-volatile resistive random access memory crossbar device comprising: a crossbar array comprising a bitline and a wordline; a hardmask comprising dielectric material and disposed over the bitline, wherein the hardmask and the bitline comprise a first sidewall and wherein the hardmask and the bitline further comprise a second sidewall on an opposing side thereof from the first sidewall; and a memory element layer and a selector layer disposed in overlying relationship, wherein the memory element layer and the selector layer in overlying relationship are further disposed in overlying relationship on the first sidewall of the bitline and hardmask, wherein the memory element layer and the selector layer are further disposed in overlying relationship over the second sidewall of the bitline and hardmask, and wherein the memory element layer and the selector layer are further disposed between the bitline and the wordline, to form a first memory element and selector pair.
