We propose a SPICE model that describes qualitatively real memristor device operation. Namely we introduce volatile effects, rate-dependent resistive switching and unipolar effects which can be tailored to influence together or separately the device's resistance. We compare our model's response to different real memristor device dynamics and conclude a high degree of similarity. We also fit our model to volatile resistive switching measured on one of our solid state TiO2 memristors.
