Title: IONICALLY CONTROLLED THREE-GATE COMPONENT
Abstract:
The invention relates to a three-gate component which can be switched by the motion of ions. The three-gate component comprises a source electrode (3), a drain electrode (3), and a channel (2) which is connected between the source electrode and the drain electrode and which is made of a material having an electronic conductivity that can be changed by supplying and/or removing ions. According to the invention, the three-gate component has an ion reservoir (5) which is contacted by means of a gate electrode and is connected to the channel in such a way that the ion reservoir (5) can exchange ions with the channel when a potential is applied to the gate electrode. It has been recognized that information can be stored in the three-gate component in the distribution of the total ions present in the ion reservoir and in the channel between the ion reservoir and the channel. The distribution of the ions between the channel and the ion reservoir changes if and only if a corresponding driving potential is applied to the gate electrode. Therefore, in contrast to RRAMs, there is no time-voltage dilemma.
