Abstract: A memory device configured as a dynamic random access memory is provided, comprising a first semiconductor device layer comprising a first bit cell and a second semiconductor device layer comprising a second DRAM bit cell. Further, at least one of a first and second interconnecting structure is provided, the first interconnecting structure extending vertically between the first and second semiconductor device layer and being arranged to form a write word line common to the gate terminal of the write transistors of the first and second bit cells, and the second interconnecting structure extending vertically between the first and second semiconductor device layer and being arranged to form a read word line common to a first source/drain terminal of the read transistors of the first and second bit cells.
