Abstract
A semiconductor device includes a first semiconductor chip including a plurality of driver circuits and an output switching circuit coupled to the plurality of driver circuits. The device also includes a second semiconductor chip and a plurality of through silicon vias provided on at least one of the first and second semiconductor chips. The output switching circuit is coupled between the plurality of driver circuits and the plurality of the through silicon vias, and outputs each of signals from the plurality of driver circuits to corresponding one of the plurality of through silicon vias.
