A storage device according to the invention has flexible architecture and free scalability. It includes an address input and a data input. It also includes an address and data evaluation unit, which is formed in such a way that it controls a controllable switching means, wherein in operation the address and data evaluation unit depends on the signals of said address and data inputs. Finally, a read/write line for a read/write signal is provided, which can be applied to a local probe data storage unit via the controllable switching means.
