Phase change memory elements using energy conversion layers, memory arrays and systems including same, and methods of making and using

摘要

A phase change memory element and method of forming the same. The memory element includes a phase change material layer electrically coupled to first and second conductive material layers. A energy conversion layer is formed in association with the phase change material layer, and electrically coupled to a third conductive material layer. An electrically isolating material layer is formed between the phase change material layer and the energy conversion layer.
