A circuit and its control method for realizing multi-layer recognition based on memristor

Abstract

A circuit for realizing multilayer recognition based on a memristor and a method for controlling the circuit, aiming to simulate the multi-state (cognition, familiarity and strangeness) cognitive ability of a biological brain. Multilayer pulse recognition is realized by adjusting the number of matched signal pulses of a second input terminal (102) and a first input terminal (101) and the amplitude of the signal pulses of the second input terminal (102), respectively. An input signal of the first input terminal (101) represents a sample signal stored in the biological brain, and an input signal of the second input terminal (102) represents a stimulus signal from an external environment received by the biological brain. The principle of such a recognition method is to regulate the recognition state of the brain for external stimulations by controlling the sample signal stored in the brain and the stimulus signal from the external environment to be matched with each other, so as to realize a multilayer recognition technology.

Description

technical field [0001] The invention belongs to the field of microelectronics and biological cognition simulation, and more specifically relates to a circuit and a control method for realizing multi-layer recognition based on a memristor. Background technique [0002] A memristor is a device that represents both ends of the relationship between charge and magnetic flux. Its resistance value changes with the passing current, that is, the change of the resistance of the memristor is related to the magnitude and direction of the current. Therefore, the change of the resistance value of the memristor can be controlled by controlling the pulse signal acting on both ends of the memristor. This control method includes pulse amplitude, pulse width, duty cycle and so on. [0003] In the traditional field of cognition, organisms' recognition of external things is divided into many levels. The organism matches the signals obtained from external things with its own memory, and awaken...
