MEMRISTORS WITH INSULATION ELEMENTS AND METHODS FOR FABRICATING THE SAME

摘要

Embodiments of the present invention are directed to nanoscale memristor devices that provide nonvolatile memristive switching. In one embodiment, a memristor device comprises an active region disposed between a first electrode and a second electrode. The device includes a first insulation element disposed between the first electrode and an outer portion of a first surface of the active region. The first insulation element is configured with one or more opening through which the first electrode makes physical contact with the active region. The device also includes a second insulation element disposed between the second electrode and an outer portion of a second surface of the active region. The second insulation element is configured with one or more opening through which the second electrode makes physical contact with the second surface.
