A solution for using elementary electrochemical components, manufactured from the same arrangement of materials and incorporated in a single electronic circuit, for information storage or for energy storage, is presented. Electrochemical components incorporating a first electrode, a second electrode and an active area between the two, can, by the application of different voltages for switching from a highly resistive state to a weakly resistive state or for switching from a state having one given electromotive force to a state having another electromotive force, be used respectively as a memory or as a battery.

Method for using electrochemical components for storage of energy and information and associated electronic circuit

A semiconductor component includes a first electrode, designated flat electrode, defining a plane; a second electrode, designated active electrode, separated from the first electrode by an electrolyte layer; a pillar, designated vertical pillar, extending essentially along an axis perpendicular to the plane defined by the flat electrode, the pillar including a third electrode, designated vertical electrode and an information storage layer, the information storage layer covering a surface of the vertical electrode; the flat electrode and the vertical pillar being laid out so as to form a memory point. In addition, the materials of the active electrode and the electrolyte layer are chosen so as to form an energy storage zone with the flat electrode.
