A brief analysis of the main SPICE models of the memristor

In the last few years, the memristor has sparked the interest of numerous researchers. The lack of a commercially available off-the-shelf device has encouraged the publication of numerous SPICE models, which are not always easy to use. We believe that unclear schematics and obscure, and sometimes flawed, codes have prevented the widespread application of yet valid models. In this paper, we devote our efforts to the clear and systematic presentation of a few remarkable SPICE models, and provide a complete library containing all working codes and essential schematics.
