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.
Claims48
A switching device comprising:
- first and second electrodes,
- an active region provided between the first and second electrodes and including a molecular system that comprises ionic complexes distributed there through,
- a control electrode for controlling an electric field applied to the active region, and
- an insulating layer adjacent the control electrode.
A memory switch comprising:
- a gate terminal,
- at least two signal terminals, and
- an active element electrically connected between the signal terminals and responsive to a signal applied to the gate terminal for switching between an on state and an off state, the active element including a molecular system and ionic complexes comprising Na ions and Cl ions distributed in the system.
A method of switching a device having a control terminal, a pair of signal terminals, and an active element electrically connected between the signal terminals and including a molecular system;
- the method comprising the steps of:
- applying to the control terminal a signal having a first polarity with respect to the signal terminals to switch the device from an off state to an on state, impedance of the active element in the on state being lower than in the off state, and
- selectively applying to the control terminal a signal having a second polarity with respect to the signal terminal, opposite with respect to the first polarity, to switch the device from the on state to the off state.
