As previously reasoned in 1971 by Leon Chua from symmetry arguments, a simple analytical device recently showed that there exists a fourth fundamental element, called a
memristor (short for
memory resistor). The device is based on nanoscale systems to enable coupling between solid-state electronic and ionic transport under an external bias voltage. The results, involving the motion of charged atomic or molecular species, provide understanding a wide range of hysteretic current-voltage behaviour observed in various nanoscale electronic devices. This inventions would definitely revolutionize electronic devices.
