    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: A metal-insulator transition (MIT) latch includes a first electrode spaced apart from a second electrode and an MIT material disposed between said first and second electrodes. The MIT material comprises a negative differential resistance (NDR) characteristic that exhibits a discontinuous resistance change at a threshold voltage or threshold current. Either the first or second electrode is electrically connected to an electrical bias source regulated to set a resistance phase of the MIT material.

    摘要: Chaotic oscillator-based random number generation is described. In an example, a circuit includes a negative differential resistance (NDR) device to receive an alternating current (AC) bias. The circuit further includes a capacitance in parallel with the NDR device, the capacitance having a value such that, in response to a direct current (DC) bias applied to the NDR device and the capacitance, a voltage across the capacitance oscillates with a chaotic period. The circuit further includes a random number generator to generate random numbers using samples of the voltage across the capacitance.

    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.
