    摘要: A nonlinear memristor includes a bottom electrode, a top electrode, and an insulator layer between the bottom electrode and the top electrode. The insulator layer comprises a metal oxide. The nonlinear memristor further includes a switching channel within the insulator layer, extending from the bottom electrode toward the top electrode, and a nano-cap layer of a metal-insulator-transition material between the switching channel and the top electrode. The top electrode comprises the same metal as the metal in the metal-insulator-transition material.

    摘要: A memristor with a controlled electrode grain size includes an adhesion layer, a first electrode having a first surface contacting the adhesion layer and a second surface opposite the first surface, in which the first electrode is formed of an alloy of a base material and at least one second material, and in which the alloy has a relatively smaller grain size than a grain size of the base material. The memristor also includes a switching layer positioned adjacent to the second surface of the first electrode and a second electrode positioned adjacent to the switching layer.

    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: 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: A hierarchical on-chip memory (400) includes an area distributed CMOS layer (310) comprising input/output functionality and volatile memory and via array (325, 330), the area distributed CMOS layer (310) configured to selectively address the via array (325, 330). A crossbar memory (305) overlies the area distributed CMOS layer (310) and includes programmable crosspoint devices (315) which are uniquely accessed through the via array (325, 330). A method for utilizing hierarchical on-chip memory (400) includes storing frequently rewritten data in a volatile memory and storing data which is not frequently rewritten in a non-volatile memory (305), where the volatile memory is contained within an area distributed CMOS layer (310) and the non-volatile memory (305) is formed over and accessed through the area distributed CMOS layer (310).

    摘要: Shiftable memory employs ring registers to shift a contiguous subset of data words stored in the ring registers within the shiftable memory. A shiftable memory includes a memory having built-in word-level shifting capability. The memory includes a plurality of ring registers to store data words. A contiguous subset of data words is shiftable between sets of the ring registers of the plurality from a first location to a second location within the memory. The contiguous subset of data words has a size that is smaller than a total size of the memory. The memory shifts only data words stored inside the contiguous subset when the contiguous subset is shifted.
