Abstract
A column redundancy circuit and method of a semiconductor memory device. The column redundancy circuit comprises a programming element for programming a repair column address; a comparing element for comparing the programmed repair column address with a column address inputted from outside to thereby generate a redundancy enable control signal according to result of the comparison; a decoding element for decoding the repair column address signal to thereby generate a decoding signal; and a redundancy column select element for compounding the decoding signal and a data input signal to thereby enable a redundancy column select signal.
