ABSTRACT:
The semiconductor memory device is provided with a readout mode in which a plurality of word data are read out from a memory cell array as a group and are subjected to a time division operation to be continuously output. The device includes a redundant unit which replaces a bit data of a defective bit present in the respective word data with a replacement data on a basis of the word data during said readout mode, thereby reconfiguring the plurality of word data.
