Embodiment Construction

[0025] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0026] Pavlov's associative memory experiment is one of the most representative experiments in the associative memory experiment, the present invention is an example to illustrate the experimental process of the present invention with Pavlov's associative memory experiment, in Pavlov's associative memory experiment, Food as an unconditioned stimulus can make the dog salivate, and the bell as a conditioned stimulus cannot make the dog salivate without training; first, the dog is given food after the bell rings, and after several training sessions, the dog starts to salivate when he hears the bell , this process represents the establishment of an associative memory of the food and the bell; the bell is then rung alone, or ...

Abstract

The invention provides an associative memory circuit and memory method based on a physical memristor. The circuit comprises a synaptic unit and a spiking neuron unit, the synapse unit comprises a memristive synapse M1 and a memristive synapse M2; the pulse neuron unit comprises a pre-synaptic neuron A, a pre-synaptic neuron B and a post-synaptic neuron C. The pre-synaptic neuron A and the pre-synaptic neuron B receive conditional stimulation signals and non-conditional stimulation signals respectively. The synaptic units and the spiking neuron units form a basic associative memory unit, and a plurality of basic associative memory units can form a biological neural network. The synaptic unit is based on a physical memristor, the defects that a traditional synaptic circuit is large in size and high in energy consumption are overcome, the integration level of the artificial neural network is improved, and the possibility is provided for an artificial neural network hardware circuit to simulate a large-scale biological neural network.

Description

technical field [0001] The invention relates to the field of associative memory circuits, in particular to an associative memory circuit and method based on physical memristors. Background technique [0002] In order to make computers and machines more intelligent, more and more researchers are working on how to build neuromorphic circuits to simulate biological neural networks. One of the important functions of biological neural network is associative memory, which is a self-learning method in human life, which enables human beings to remember the relationship between two events. The use of neuromorphic circuits to simulate associative memory is also the basis for further research on the use of neuromorphic circuits for various information processing. Therefore, the realization of associative memory functions in circuits is of great significance to the development of neuromorphic circuits. [0003] Memristor is the fourth basic circuit element besides resistance, inductanc...
