Abstract
A semiconductor device may include a repair address storage circuit, an address comparison circuit, and a word line selection circuit. The repair address storage circuit may store a first repair address and a second repair address. The address comparison circuit may generate a first comparison signal by comparing an input address and the first repair address, and may generate a second comparison signal by comparing the input address and the second repair address. The word line selection circuit may generate a first redundancy word line select signal corresponding to the first comparison signal and a second redundancy word line select signal corresponding to the second comparison signal, based on the first comparison signal and the second comparison signal.
