Claim 0:
1. A semiconductor apparatus comprising:
a first semiconductor chip configured to, based on first chip master information and swapping information, output a first chip end output signal through a first pad, receive a first chip end input signal that is received through the first pad, and receive a first chip start input signal that is received through a second pad, the first semiconductor chip configured to perform a calibration operation of the first semiconductor chip based on a calibration command signal and the first chip start input signal; and
a second semiconductor chip configured to, based on second chip master information and the swapping information, output a second chip start output signal through a first pad, output a second chip end output signal through a second pad, and receive a second chip end input signal that is received through the second pad, the second semiconductor chip configured to perform a calibration operation of the second semiconductor chip based on the second chip end input signal,
wherein the second semiconductor chip is disposed such that the first pad of the second semiconductor chip faces the second pad of the first semiconductor chip and the second pad of the second semiconductor chip faces the first pad of the first semiconductor chip,
wherein the first pad of the second semiconductor chip is coupled to the second pad of the first semiconductor chip, and
wherein the second pad of the second semiconductor chip is coupled to the first pad of the first semiconductor chip.
