摘要： An integrated circuit includes a memory cell with a resistance changing memory element. The resistance changing memory element includes a first electrode, a second electrode, and a resistivity changing material disposed between the first and second electrodes, where the resistivity changing material is configured to change resistive states in response to application of a voltage or current to the first and second electrodes. In addition, at least one of the first electrode and the second electrode comprises an insulator material including a self-assembled electrically conductive element formed within the insulator material. The self-assembled electrically conductive element formed within the insulator material remains stable throughout the operation of switching the resistivity changing material to different resistive states.
