Abstract
A novel switching device is provided with an active region arranged between first and second electrodes and including a molecular system and ionic complexes distributed in the system. A control electrode is provided for controlling an electric field applied to the active region, which switches between a high-impedance state and a low-impedance state when the electrical field having a predetermined polarity and intensity is applied for a predetermined time.
