Abstract
A three dimensional memory includes flat electrodes, each defining a plane; a vertical electrode, extending essentially along an axis perpendicular to the plane defined by each flat electrode; floating electrodes, each situated between a flat electrode and the vertical electrode; first layers of an insulating material, each flat electrode being separated from the preceding and/or following flat electrode by a first layer of an insulating material; first layers of a first active material, each layer of an active material separating a flat electrode from the floating electrode that is associated therewith; a second layer of a second active material separating the vertical electrode from the floating electrodes. The first active material forms a selector or a memory point and the second active material forms a memory point or a selector. Each flat electrode includes first, second and third sub-layers made of, respectively, first, second and third conductive materials.
