Abstract
In a semiconductor apparatus of the present invention, a plurality of circuit components are provided. A first bus interconnects the circuit components. A second bus interconnects the circuit components. A switching unit outputs a select signal that causes each circuit component to select one of the first bus and the second bus when transmitting a signal from one of the circuit components to another. The second bus has a size larger than a size of the first bus.
