Abstract

Official abstract text for this publication.

Memory cells and memory cell structures having a number of phase change material gradients, devices utilizing the same, and methods of forming the same are disclosed herein. One example of forming a memory cell includes forming a first electrode material, forming a phase change material gradient on the first electrode material, and forming a second electrode material on the phase change material gradient.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of forming a memory cell, comprising: forming a first electrode material coupled to a first conductive line; forming a phase change material gradient on the first electrode material, wherein a phase change material comprises a chemical gradient with an active material that actively changes between an amorphous state and a crystalline state that is formed at least partially by a predetermined selection of a plurality of different chemicals to be de…
