A full-function memristive pavlov associative memory circuit with inter-stimulus interval effect

Time interval between stimuli plays a critical role in Pavlov classical conditioning. In this paper, a full-functional memristive Pavlov associative memory circuit with inter-stimulus interval effect is proposed. Compared with previous works, the proposed circuit extends the Pavlov associative memory with time interval to three complex situations of conditioning and realizes bionic associative memory learning curves called inter-stimulus interval effect. On this basis, the phenomena related to time interval in classical conditioning, blocking and facilitation, are implemented. PSPICE is used to simulate the whole circuit, and the simulation results demonstrate above functions. Furthermore, an application on classification is extended on the basis of the proposed circuit. The application circuit is also verified by the simulation results in PSPICE. This paper provides a reference to associative memory based on memristor in complex time situations.
