Dynamical resistive switching of a generic memristor model: Analysis and simulation

The memristors was theorized by Leon O. Chua in 1971 as a passive two-terminal electronic device that changes its resistive state depending on the current or voltage history through the device. Since the first fabrication of the memristor by HP Labs in 2008, it has been extensively studied for wide electronic applications. Thus, many SPICE models have been proposed to describe the behavior of memristor. All these models are focused on the pinched hysteresis loop phenomenon, which takes various shape, depending on their different properties. In this paper, we study the dynamical behavior of memristor. We use a simple and flexible SPICE memristor model to demonstrate that this model accounts for four different types of a memristor: the bipolar memristor behavior, the unipolar memristor behavior, the bipolar with forgetting effect and the reversible process between the bipolar and the unipolar behavior.
