Abstract
A semiconductor apparatus includes a fuse array, storage circuit, parity circuit, fuse data register, parity data register, and error correction circuit. The fuse array stores information about fail addresses and outputs the stored information as fuse data during a boot-up operation. Wherein, the storage circuit stores the fuse data and outputs it as a storage signal and the parity circuit performs a parity operation based on the storage signal and outputs a result of the parity operation as a parity signal, the fuse data register receives and stores the fuse data and outputs the stored data as a fuse register output signal. The parity data register receives and stores the parity signal and outputs the stored information as a parity register output signal, the error correction circuit corrects an error of the fuse register output signal based on the parity register output signal and outputs the error-corrected signal as repair information.
