Semiconductor device


A semiconductor device includes: a plurality of repair fuse circuits configured to each program a repair target address; and an enable signal generation circuit configured to generate at least one enable signal in response to a source signal and provide the enable signal to each of the repair fuse circuits in common. Since the semiconductor device may iteratively generate a rupture enable signal through a feedback scheme, the area occupied by a circuit, such as a shift register or a d flip-flop may be saved..
