In this paper, a behavioral SPICE memristor model for digital logic implementation is presented and demonstrated in LTSpice. We show binarized state switching and voltage thresholding in the model, which are both important features in practical digital systems. The use of this SPICE model is straightforward and intuitive because almost all parameters in the model can be changed according to the application, including the threshold voltage and the memristance. The LTSpice circuit simulation shows the same characteristics as the original MATLAB numerical implementation, which means that the circuit-level SPICE model can be integrated with other designs. Three types of memristor digital logic circuits are simulated with the LTSpice model with positive results, which proves that the behavioral memristor model has potential application in digital system design.
