    摘要: Circuitry is provided that closely emulates biological neural responses. Two astable multivibrator circuits (AMCs), each including a negative differential resistance device, are coupled in series-circuit relationship. Each AMC is characterized by a distinct voltage-dependant time constant. The circuitry exhibits oscillations in electrical current when subjected to a voltage equal to or greater than a threshold value. Various oscillating waveforms can be produced in accordance with voltages applied to the circuitry.

    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 memory array with write feedback includes a number of row lines intersecting a number of column lines, a memory element connected between one of the row lines and one of the column lines, an electrical condition supply to be selectively applied to one of the row lines; and a feedback control loop to control an electrical condition supplied by the electrical condition supply. A method for setting the state of a memory element within a memory array includes applying an electrical condition to the memory element within the memory array, sensing a resistive state of the memory element, and controlling the electrical condition based on the sensed resistive state to cause the memory element to reach a target resistance.

    摘要: A memristor has a first electrode, a second electrode parallel to the first electrode, and a switching layer disposing between the first and second electrodes. The switching layer contains a conduction channel and a reservoir zone. The conduction channel has a Fermi glass material with a variable concentration of mobile ions. The reservoir zone is laterally disposed relative to the conduction channel, and functions as a source/sink of mobile ions for the conduction channel In the switching operation, under the cooperative driving force of both electric field and thermal effects, the mobile ions are moved into or out of the laterally disposed reservoir zone to vary the concentration of the mobile ions in the conduction channel to change the conductivity of the Fermi glass material.
