Abstract
A repair circuit of a semiconductor apparatus includes a transmission control unit configured to generate first through nth (n is an integer equal to or greater than 2) control signals in response to a repair information signal, and enable all mth through nth control signals when the repair information signal indicating an mth (m is an integer equal to or greater than 1 and equal to or less than n) TSV is inputted; transmission units configured to allocate transmission paths for first through nth signals to first through nth TSVs and a repair TSV in response to the first through nth control signals; and receiving units configured to receive the signals transmitted from the first through nth TSVs and the repair TSV in response to the first through nth control signals.
