There are three fundamental passive circuit elements, resistors, capacitors, and inductors, but it was reasoned that there should be a fourth fundamental element, called a memristor, which has until now not been realized in a physical system. A fresh analysis of the concept shows that memristance arises naturally in nanoscale systems where solid state electronic and ionic transport are coupled under an external bias voltage.
