Abstract
An integrated circuit includes an array of diodes and an electrode coupled to each diode. The integrated circuit includes a layer of resistance changing material coupled to the electrodes and bit lines coupled to the layer of resistance changing material. The layer of resistance changing material provides a resistance changing element at each intersection of each electrode and each bit line.
