Embodiment Construction

[0016] Below in conjunction with accompanying drawing, the present invention will be further described by examples.

[0017] The bipolar resistive memristor has two polarities. If the absolute value of the applied voltage is large enough, when the positive pole is connected to the positive voltage and the negative pole is grounded, the resistance value of the bipolar resistive memristor will decrease. On the contrary, when When the negative pole is connected to the positive voltage and the positive pole is grounded, the resistance value of the bipolar resistive memristor will increase.

[0018] figure 2 (a) is a circuit diagram in which the positive pole of a single bipolar resistive memristor is connected to the positive input terminal, and the negative pole is connected to the negative input terminal, figure 2 (b) for if figure 2 (a) A plot of the resistance of the bipolar resistive memristor as a function of the height and width of the input pulse. like figure 2 As ...

Abstract

The invention discloses a self routing unit circuit and a control method thereof. The circuit of the present invention is suitable for a large-scale interconnected neural network system. The synaptic connection of a front neuron and three or more back neurons employ the self routing circuit unit. Three or more branches in parallel connection are provided, and each parallel branch is formed by one or more bipolar resistive memristors. Each branch has a different structure, with differences of the number of the resistive memristors, the connection directions of polarities and parallel and series connection modes, the self routing unit circuit corresponding to specific voltage is formed. According to the circuit of the invention, the circuit can automatically choose to transmit a signal to the back neurons, the circuit is simple, a structure is small and large-scale integration is facilitated; the circuit is a non volatile circuit, and once set, the circuit is not needed to be reset again when a condition is unchanged.

Description

technical field [0001] The invention relates to a routing unit circuit, in particular to a self-routing unit circuit suitable for a large-scale interconnected neural network system. Background technique [0002] Digital computer is an important product of human technological progress in the 20th century, and its influence is reflected in all aspects of people's lives. Compared with digital computers, neural computers have great potential in terms of intelligence, large-scale computing power, storage and computing integration, and are likely to become a powerful substitute for digital computers. In the neural network system, its basic unit is a neuron, and there is a large-scale interconnection between neurons. This interconnection is called a synapse, and the signal is transmitted from the pre-neuron to the post-neuron through the synaptic connection. It is precisely because of these large-scale synaptic connections that neural computers have strong computing, recognition, ...
