Abstract

An electronic device includes a first electrode made of an inert material; a second electrode made of a soluble material; a solid electrolyte made of an ion-conductive material, wherein the first and second electrodes are in contact respectively with one of the faces of the electrolyte, either side of the electrolyte, wherein the second electrode supplies mobile ions flowing in the electrolyte towards the first electrode, to form a conductive filament when a voltage is applied between the first and second electrodes. The second electrode is a confinement electrode that includes an end surface in contact with the electrolyte which is less than the available surface of the electrolyte, such that confinement of the contact area of the confinement electrode on the solid electrolyte is obtained.
