  • MEMRISTOR AND METHODS FOR MAKING THE SAME
    Publication number: 20160141492
    Abstract: An example of the memristor includes a bottom electrode, a switchable material positioned on the bottom electrode, and a cured negative or positive resist that forms an interlayer dielectric positioned on the switchable material. An open area is formed in the interlayer dielectric. The open area exposes a surface of the switchable material. A top electrode is positioned in contact with the exposed surface of the switchable material at the open area.
