Abstract
Memristor, memcapacitor and meminductor are the promising circuit elements with the potential of bringing significant changes in the field of new memory in nano-electronic devices. This paper presents a simple model of a meminductor whose inductance can be varied by an external current source without employing any memrisitve system. The adequate of this model is verified by its fingerprints characteristics.
