Comment: Is memristor a dynamic element?
نویسنده
چکیده
In [1] the authors present a charge/flux formulation of the equations of memristive circuits which seemingly show that the memristor should not be considered as a dynamic circuit element. We show in this Letter that the authors' approach implicitly reduces the dynamic analysis to a certain subset of the state space in a way such that the dynamic contribution of memristors is hidden. This reduction might entail a substantial loss of information, regarding e.g. the local stability properties of the circuit. Two examples illustrate this. We conclude that the memristor, even with its unconventional features, must be considered as a dynamic element.

In 1971 a “missing memristor” was proposed by a circuit theorist named Leon Chua as a 4 fundamental passive circuit element defined by a non-linear relationship between electric charge and magnetic flux linkage. In 2008 a research group from Hewlett-Packard led by Stan Williams claimed credit for finding this “missing memristor” based on the observation of a zero-crossing hysteresis effect. I r...

Memory resistor or memristor is already fabricated successfully using current nano dimension technology. Based on its unique hysteresis, the amount of resistance remains constant over time, controlled by the time, the amplitude, and the polarity of the applied voltage. The unique hysteretic current-voltage characteristic in the memristor causes this element to act as a non-volatile resistive me...
