Mem-elements for Neuromorphic Circuits with Artificial Intelligence Applications

Preface

In 1971, Leon Chua, in a seminal paper, extrapolated a conceptual symmetry between the nonlinear resistor (voltage vs. current), nonlinear capacitor (voltage vs. charge), and nonlinear inductor (magnetic flux linkage vs. current). He then inferred the possibility of a new element as another fundamental nonlinear circuit element linking magnetic flux and charge. In contrast to a linear (or nonlinear) resistor the new element has a dynamic relationship between current and voltage including a memory of past voltages or currents.

This new element's resistance depends on the integral of the input applied to the terminals. Since the element “remembers” the amount of current that last passed through, it was ...
