According to one embodiment, a semiconductor device includes receiving terminals on a surface of a substrate to receive first signals and transmitting terminals on the surface of the substrate to transmit second signals. The transmitting terminals are symmetrically positioned on the surface of the substrate with respect to the receiving terminals at a substantially 90 degree rotation about a rotation center position. The ordering of the transmitting terminals along the surface of the substrate from the rotation center position matches the ordering of the receiving terminals along the surface of the substrate from the rotation center position.
