Abstract

A semiconductor memory device having normal columns and redundant columns includes normal column decoders for designating the normal columns and redundant column decoders for designating the redundant columns so that the bits from the normal columns are combined with the bits from the redundant columns so as to provide an entire byte. The normal column decoders are to be operated simultaneously with the redundant column decoders.
