Abstract
A dynamic random access memory device has a plurality of memory cell arrays, a plurality of sense amplifier units associated with the plurality of memory cell arrays, and a combined unit of data registers and a pointer for serially supplying read-out data bits to a serial output data bus, wherein each sense amplifier unit is shared between two of the memory cell arrays and the combined unit is also shared between two sense amplifier units so that the dynamic random access memory device occupies a small semiconductor chip.
