| Zusammenfassung: | A method for producing an integrated semiconductor memory configuration includes forming two capacitor modules for each selection transistor from the front and rear side of the substrate wafer respectively. Thus, a higher packing density of memory cells is engendered by the utilization of the rear side of the wafer. A twofold memory read signal can be used for the same cell surface area. Conditions in addition to "0" or "1" can also be saved for each selection transistor in a ferroelectric memory configuration, if the two capacitor modules have a different structure in terms of layer thickness, surface area, or material. |
