Positive voltages and negative voltages are applied to adjust memristance in most memristive circuits. This paper presents a memristance changing circuit in which memristance is changed only by the positive voltage. A mathematical calculation method is proposed to analyze the memristance change approximately. Furthermore, memristance changing circuits are utilized as synapses to construct a neural network to imitate full-function Pavlov associative memory. Compared to the classical Pavlov associative memory, the full-function Pavlov associative memory contains additional food forgetting and ring forgetting processes. The forgetting processes will be triggered in the condition that either the food or the ring is given to the dog after the learning processes. The learning and forgetting time of the associative memory can be obtained by the proposed mathematical calculation method in advance approximately.
