Memristor-based neural network circuit of pavlov associative memory with dual mode switching

There are many learning modes in associative memory, but most of memristor-based Pavlov associative memory circuits only have a single mode. A learning circuit that can realize Pavlov associative memory with dual-mode switching is designed and verified by the simulation results. The designed circuit consists of the auditory (visual) synapse, auditory (visual) control voltage module and auditory (visual) inhibition module. This paper considers two different learning modes, auditory mode and visual mode. The modes can run not only separately but also alternately. Besides, the paper also considers the inhibition relationship between learning modes and reflects the relationship by adjusting the influence of mode switching period on the learning speed of modes. As a widespread phenomenon in the natural world, mode inhibition of associative memory can be regarded as a psychological process of living things under different external stimulus. Mode inhibition is an interesting subject, which can allow the artificial neural network to mimic more realistic situations of memory. The dual mode switching is an essential part of life, which can provide more references for the practical application of memristor.
