The learning excitation signal is used for calling the auditory module and the visual module, auditory mode learning and visual mode learning can perform mode switching, the purpose of dual-mode switching learning is achieved, and the problem that a learning memory circuit can only perform single-mode learning is solved.

Description

technical field [0001] The invention relates to the technical field of digital-analog circuits, in particular to a learning and memory circuit based on memristor-based Pavlovian dual-mode switching. Background technique [0002] In 2008, Hewlett-Packard prepared a resistor with memory properties in the laboratory, which proved to be the fifth passive electronic component proposed many years ago --- memristor. As a new type of component, scholars from all over the world pay more and more attention to memristors and begin to study them from various aspects. With the deepening of people's understanding of the concept of memristors, it is found that the characteristics of memristors are very similar to synapses in biological nerves, which can imitate some functions of the brain, so as to simulate memory learning of biological behavior. Judging from the existing literature, circuit simulation of biological memory behavior has become an extremely important part of memristor resea...

Problems solved by technology

[0004] Aiming at the technical problem that auditory mode is the traditional learning mode of Pavlovian associative memory, but single mode learning cannot actually reflect the diversity of learning and memory in life, the present invention proposes a Pavlovian dual mode based on memristor The switched learning and memory circuit can not only realize the learning and memory of auditory and visual modes, but also can switch the learning and memory of auditory and visual modes, realizing the diversity of learning and memory in a real sense
