    Abstract: The invention relates to a memory circuit arrangement comprising a memory cell region (12) that contains a plurality of memory cell transistors (T00 to T21). The memory cell transistors (T00, T01) in a column are selected by means of a selection transistor (TD0). Said selection transistor (TD0) is a triple control-region transistor, whose control region extends as far as isolation trenches (G0, G1). The latter (G0, G1) also isolate the memory cell transistors (T00, T10) of different columns in the memory cell field (12). Said arrangement increases the level of integration.

    Abstract: A method for the production of bitlines (40) for a memory cell array, firstly comprises the step of preparation of a layer structure from a substrate (10) with a transistor trough (12) implanted in a surface thereof, a memory medium layer sequence (20), provided on the surface of the substrate (10) and a gate region layer (22), provided on the memory medium layer sequence (20). Bitline recesses are generated in the gate region layer (22), extending to the memory medium layer sequence (20). Insulating separation layers (36) are then generated on lateral surfaces of the bitline recesses, whereupon a source/drain implantation (38) is carried out after a complete or partial removal of the memory medium layer sequence (20) in the region of the bitline recesses. The substrate is completely exposed in the region of the bitline recesses should this not be the case before the implantation. A metallisation is then generated on the exposed substrate for production of metallic bitlines (40). Said metallisation is insulated from the gate region layer (22) by means of the insulating separation layers (36).

    Abstract: A memory circuit arrangement and fabrication method thereof are presented in which the parts of the memory circuit arrangement are situated on two different substrates. An integrated memory cell array is situated on one substrate. An integrated control circuit that controls access to the memory cells is situated on the other (logic circuit) substrate. The control circuit controls sequences when reading, writing or erasing content of a memory cell. The logic circuit substrate also contains a CPU and encryption coprocessor. The memory circuit contains a sense amplifier, with the aid of which the memory state of a memory cell can be determined, and a decoding circuit that selects a word or bit line.
