Abstract

A semiconductor memory device is provided in which no delay in writing of data occurs due to increases in the output load of the data input circuit, and which is also compatible with various bit configurations. The device comprises a plurality of data input circuits for inputting data from an external source, and a plurality of data write circuits for writing data input from the plurality of data input circuits to a memory cell array. The data to be stored is input from an external source by selectively using the plurality of data input circuits, and then each bit to be stored is distributed to the plurality of data write circuits according to the bit configuration of the data. Of the plurality of data input circuits, data input from a specific data input circuit is distributed to one of the plurality of data write circuits via another data input circuit.
