Embodiment Construction

[0026]In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] To achieve the above object, the present invention provides a memristor-based episodic memory circuit. According to the basic model of episodic memory, its circuit is divided into two parts, encoding and retrieval, which respectively realize the function of encoding process and retrieval process in the episodic memory model. The scene memory encoding circuit includes a first memristor M1, a second memristor M2, a third memristor M3, a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4 and a fifth resistor R5 ; One end of the first memristor M1 is used as the f...

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 ...
