Memristor-based episodic memory circuit and operation method thereof

Abstract

The invention discloses a memristor-based episodic memory circuit and an operation method thereof. The episodic memory circuit includes a coding circuit and a retrieval circuit; the coding circuit codes an event according to the event itself and the relevant characteristics of the event and stores codes in the circuit, deletes stored information through erasing signals, and adopts generated engram signals as the input signals of a low-stage circuit; and the retrieval circuit can matches the engram signals with retrieval signals so as to generate a corresponding episodic memory behavior. With the memristor-based episodic memory circuit and the operation method thereof of the invention adopted, the episodic memory behaviors of living creatures can be simulated according to applied relevant operation pulses.

Description

technical field [0001] The invention belongs to the field of artificial neural networks, and more specifically relates to a memristor-based scene memory circuit and an operation method thereof. Background technique [0002] Episodic memory is a declarative memory that is different from semantic memory. It is characterized by the ability to match the memory traces stored in the brain with the stimulus signals (retrieval cues) perceived from the outside world, thereby generating episodic signals, and through the episodic signals To control the biological behavior of recall and recognition in organisms. Episodic memory is an advanced cognitive behavior, which constitutes the connection of organisms to events, their occurrence time and place, which is of great significance to the basic life activities of living organisms. The biological basis of episodic memory is joint learning. In its model, episodic memory is generally divided into two processes, namely the encoding process ...

AI Technical Summary

Problems solved by technology

[0003] At present, the research on episodic memory in artificial neural network is in its infancy. Usually, some conceptual models of episodic memory and corresponding operation methods are provided through simulation methods. It is difficult to realize specific episodic memory circuits to simulate corresponding episodic memory. Function
