Embodiment Construction

[0069] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0070] A neuron and a neuron circuit constructed by a brain-like device memristor, wherein:

[0071] The neuron includes a synapse and a nucleus, and the synaptic front end of the neuron is constructed by using a semiconductor material selector, a multi-configuration device memristive device, and a low-resistance nanowire.

[0072] The semiconductor material selector can be made of materials with excellent performance. The memristor at the front end of the synapse can be a low-range, stable memristor, or it can be designed separately according to the actual situation. The memristor used is a high-range, multi-value memristive device, and the nanowires used can be selected from the latest optimized materials, or can be selected according to actual conditions.

[0073] The core part includes CMOS device N type and CMOS device P type, ...

Abstract

The invention aims at the special requirement of the memristor as the electronic component of the processor, presents a neuron and neuron circuit based on the memristor of brain-like device, which canrealize the signal storage and processing similar to human neuron cell, and its single neuron cell can be extensively connected with hundreds of memristors, which provides a very feasible circuit design way for the large-scale use of memristors. In combination with other types of electronic devices such as CMOS tubes, a selector, a nanowire, and pulse design, the invention creatively solves the polysynaptic connection in biology of neuron cell designed by memristor as the core device of processor, forward stimulation, backward stimulation, nuclear storage, synaptic front-end, protruding back-end and other biological design issues, to achieve (forward and backward) signal processing within neurons and transmission between neurons, and build the corresponding neuronal cells and neural network circuits.

Description

technical field [0001] The invention relates to the technical field of neural networks, in particular to a neuron and a neuron circuit constructed by a brain-like device memristor. Background technique [0002] Although the existing neuron network circuits built with memristors use memristors in their framework, they still have limitations in the number and scale of memristors used. [0003] In reality, heavy reliance on traditional operational amplifiers and other transistor devices cannot be avoided. Not only is the limit increased in terms of use, but it is also very limited in practical application. [0004] In terms of signal processing, other neuron network circuits built with memristors currently process specific signals and cannot handle complex calculation problems in neural networks. Contents of the invention [0005] Aiming at the special requirements of the memristor as a processor electronic component, the present invention proposes a neuron and a neuron cir...
