Abstract:
1. A semiconductor device comprising: a plurality of semiconductor chips laminated to each other, the semiconductor chips including at least first and second semiconductor chips; and a plurality of through silicon vias electrically connected in common to the plurality of semiconductor chips, wherein the first semiconductor chip stores switching information that specifies one or more of the penetration electrodes to be used for data transfer, and the first semiconductor chip transfers the switching information to the second semiconductor chip, wherein the first semiconductor chip includes a first switching circuit that selects one or more of the penetration electrodes to be used for data transfer based on the switching information, and the second semiconductor chip includes a second switching circuit that selects one or more of the penetration electrodes to be used for the data transfer based on the switching information transferred from the first semiconductor chip, and wherein each of the penetration electrodes selected by the first switching circuit is electrically connected to an associated one of the penetration electrodes selected by the second switching circuit.
