Capacitive matrix arrangement and method for actuation thereof

A capacitive matrix arrangement, comprising an active medium, which is embedded in a layer between a first set and a second set of respective parallel addressing electrodes, wherein the addressing electrodes of the first set form word lines and the addressing electrodes of the second set form bit lines of the capacitive matrix arrangement, wherein the word lines and the bit lines intersect at crossing points and capacitor cells with an intervening active medium are arranged at the crossing points, being selectable by actuation of the word lines and the bit lines, wherein word lines at least in an area of the crossing points consist of a material with variable Debye length, i.e., a material with variable mobile charge carrier concentration, and are arranged between the active medium and a non-active dielectric, forming a layered arrangement, and the layered arrangement is situated between a reference electrode and the bit lines, and wherein

• a first layer of the layered arrangement is chosen such that the active medium as seen from a word line is situated on a side);
• with the reference electrode and
• alternatively a second layer of the layered arrangement is chosen such that the active medium as seen from the word line is situated on with the bit lines.
