Abstract
A semiconductor memory device which includes a plurality of memory cell array blocks, each block including 2 partial blocks selectable in response to n address bits among a plurality of bits address. A partial block select signal generator is used for selecting ½ partial blocks of the 2 partial blocks in each of the plurality of memory cell array blocks by selecting the state of corresponding address bits among the n address bits. A method for repairing a semiconductor memory device which includes a plurality of memory cell array blocks and 2 partial blocks selected by the plurality of memory cell array blocks each responding to n address bits among a plurality of address bits, the method includes selecting only the ½ functional partial blocks of the 2 partial blocks in each of the plurality of memory cell array blocks by selecting the state of corresponding address bits among the n bits of address information.
