Abstract
A redundant circuit includes a plurality of bit line sense amp arrays including different local data buses, sharing one bit line sense amp, and being formed adjacently to each other, an input/output fuse unit for outputting a selection signal with different logic state depending on whether or not a first fuse is cut upon activation of a row active operation control signal, a fuse set for providing a redundant signal with different logic state based on whether or not a second fuse is cut and repair addresses upon activation of the row active operation control signal, and a redundant controller for logically operating the selection signal, the redundant signal and a strobe signal to thereby generate a bus control signal to selectively connect the bit line sense amp to the different local data buses.
