A semiconductor apparatus may include a fuse cell array, an address generation circuit, a control circuit, and a command generation circuit. The fuse cell array may store a fail address. The address generation circuit may generate a copy address according to test information containing the fail address. The control circuit may control a repair operation including enabling a copy start signal according to the test information and storing the fail address in the fuse cell array according to a copy done signal. The command generation circuit may generate an address and a plurality of commands for a data copy operation according to the copy start signal and enable the copy done signal when the data copy operation is completed.
