Abstract
A column repair circuit of a semiconductor memory device including a plurality of memory cell array blocks each having the different number of wordlines comprises a predecoder, a block selector, a unit selector and a fuse means. The predecoder decodes a row address. The block selector generates block selecting signals to select the memory cell array blocks. The unit selector generates unit selecting signals to select a size of a row corresponding to the selected memory cell array. The fuse means generates a column repair control signal activated when a column repair is performed on the selected memory cell array block. The column repair circuit performs a column repair operation by a memory cell array block unit, thereby improving column repair efficiency and reducing the number of column repair fuses.
