Abstract
Official abstract text for this publication.
Resistance variable memory cells having a plurality of resistance variable materials and methods of operating and forming the same are described herein. As an example, a resistance variable memory cell can include a plurality of resistance variable materials located between a plug material and an electrode material. The resistance variable memory cell also includes a first conductive material that contacts the plug material and each of the plurality of resistance variable materials and a second conductive material that contacts the electrode material and each of the plurality of resistance variable materials.
First claim
Opening claim text (preview).
What is claimed is: 1. A resistance variable memory cell, comprising: a plurality of resistance variable materials formed between a plug material and an electrode material, wherein each of the plurality of resistance variable materials has a different respective thickness; a first conductive material that contacts the plug material and each of the plurality of resistance variable materials; and a second conductive material that contacts the electrode material and each of the p…
