ABSTRACT:
A method for transmitting a data stream from a circuit unit to a memory cell array includes receiving the data stream and demultiplexing it in response to a control signal, thereby dividing the data stream into a storage data stream and a mask data stream. The storage data stream is then buffered into a register unit, where it is divided into data stream components buffered in corresponding data register components on the basis of a clock signal and an address signal provided to the register unit. Meanwhile, the mask data stream is buffered in a mask register of the register unit. A composite data stream is then formed by combining selected data stream components in response to information provided by a data mask unit from the mask data stream buffered in the mask register. Data corresponding to this composite data stream is then provided to the memory cell array for storage therein.
