Abstract
A vertically oriented diode for use in delivering current to a multi-state memory element in a memory cell. A vertical diode may be disposed in a diode container extending downwardly from a top of a silicon or oxide layer, and may be formed of a combination of silicon and/or metal layers disposed proximate to inner surfaces of a diode container. A multi-state memory element may be formed of a multi-state material, such as a chalcogenide, above a diode to complete a memory cell.
