Abstract:
1. An electronic device comprising: a first electrode made of an inert material; a second electrode made of a soluble material for supplying mobile ions; 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 said electrolyte, wherein, when a voltage is applied between the first and second electrodes, the second electrode supplies the mobile ions flowing in the electrolyte towards the first electrode, in order to form a conductive filament between the first electrode and the second electrode; wherein the second electrode made of soluble material is a confinement electrode, wherein said confinement electrode comprises an end surface in contact with the electrolyte which is less than the available surface of the electrolyte, such that confinement of a contact area of said confinement electrode on the solid electrolyte is obtained, and wherein the volume of the electrolyte is chosen such that a surface of a first end of the electrolyte in contact with the first electrode is strictly less than a surface of a second end of the electrolyte opposite the first end.
