    摘要: In one example, an oxide-based negative differential resistance comparator circuit includes a composite NDR device that includes a first electrode, a first thin film oxide-based negative differential resistance (NDR) layer in contact with the first electrode and a central conductive portion. The composite NDR device also includes a second thin film oxide-based NDR layer disposed adjacent to the first NDR layer and a second electrode. A resistor may be placed in series with the composite NDR device and an electrical energy source can apply applying a voltage across the first electrode and second electrode. The composite NDR device produces a threshold based comparator functionality in the comparator circuit.

    摘要: A method of changing a state of a memristor having a first intermediate layer, a second intermediate layer, and a third intermediate layer positioned between a first electrode and a second electrode includes applying a first pulse having a first bias voltage across the memristor, wherein the first pulse causes mobile species to flow in a first direction within the memristor and collect in the first intermediate layer thereby causing the memristor to enter into an intermediate state and applying a second pulse having a second bias voltage across the memristor, in which the second pulse causes the mobile species from the first intermediate layer to flow in a second direction within the memristor and collect in the third intermediate layer, wherein the flow of the mobile species in the second direction causes the memristor to enter into a fully changed state.

    摘要: Embodiments of the present invention are directed to nanoscale memristor devices that provide nonvolatile memristive switching. In one embodiment, a memristor device (100) comprises an active region (102), a first electrode (104) disposed on a first surface of the active region, and a second electrode (106) disposed on a second surface of the active region, the second surface opposite the first surface. The first electrode is configured with a larger width than the active region in a first direction, and the second electrode is configured with a larger width than the active region in a second direction. Application of a voltage to at least one of the electrodes produces an electric field across a sub-region (108) within the active region between the first electrode and the second electrode.
