Abstract: A three-port component comprises a source electrode, a drain electrode, and a channel, which is corrected between the source electrode and the drain electrode and which is made of a material haying an electronic conductivity that can be varied by supplying and/or removing ions. The three-port component comprises an ion reservoir, which is in contact with a gate electrode, and which is connected to the channel so that the reservoir is able to exchange ions with the channel when a potential is applied to the gate electrode. Information can be stored on the three-port component by distributing the total number of ions, which are present in the ion reservoir and the channel, between the ion reservoir and the channel. The distribution of ions in the channel and the ion reservoir changes when, and only when, a corresponding driving potential is applied to the gate electrode. Thus, in contrast to RRAMS, there is no time-voltage dilemma.
