Abstract
A nonvolatile memory device and method for forming a resistive switching memory element, with improved lifetime and switching performance. A nonvolatile memory element includes resistive switching layer formed between a first and second electrode. The resistive switching layer comprises a metal oxide. One or more electrodes include a dopant material to provide the electrode with enhanced oxygen-blocking properties that maintain and control the oxygen ion content within the memory element contributing to increased device lifetime and performance.
