Abstract
A semiconductor apparatus includes first and second vias, a first circuit unit, a second circuit unit and a third circuit unit. The first and second vias electrically connect a first chip and a second chip with each other. The first circuit unit is disposed in the first chip, receives test data, and is connected with the first via. The second circuit unit is disposed in the first chip, and is connected with the second via and the first circuit unit. The third circuit unit is disposed in the second chip, and is connected with the first via. The first circuit unit outputs an output signal thereof to one of the first via and the second circuit unit in response to a first control signal.
