Abstract
An electronic device includes a first electrode, a second electrode and a solid electrolyte having a base of an ion conducting material. The device remains in the highly resistive state for as long as a first threshold voltage between the first electrode and the second electrode is not reached. The device switches from the state of high resistance to the state of low resistance when the potential difference between the first electrode and the second electrode is equal to or greater than the first threshold voltage. The device switches from the state of low resistance to the state of high resistance when the potential difference between the first electrode and the second electrode equal to or greater than this first threshold voltage is removed and as it decreases it reaches a second positive voltage threshold strictly lower than the first threshold voltage.
