Abstract
A repair circuit of a semiconductor apparatus includes a plurality of through-silicon vias including repeated sets of one repair through-silicon via and an M number of normal through-silicon vias; a transmission unit configured to multiplex input data at a first multiplexing rate based on control signals, and transmit the multiplexed data to the plurality of through-silicon vias; a reception unit configured to multiplex signals transmitted through the plurality of through-silicon vias at a second multiplexing rate based on the control signals, and generate output data; and a control signal generation unit configured to generate sets of the control signals based on an input number of a test signal.
