Abstract:
1. A repair circuit of a semiconductor apparatus, comprising: a plurality of through-silicon vias including one repair through-silicon via and an M number of normal through-silicon vias which are repeatedly disposed; 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 control signals, and generate output data; and a control signal generation unit configured to generate the control signals based on an input number of a test signal, wherein all the one repair through-silicon vias are configured to replace any one of a previously numbered failed through-silicon via and a subsequently numbered failed through-silicon via by the transmission unit and the reception unit based on the control signals.
