Abstract
A semiconductor device includes: first transmission wirings each transmitting a small-amplitude signal between one of a plurality of first drivers and one of a plurality of receivers; a second transmission wiring transmitting a reference signal connected to each of the plurality of receivers; and a second driver outputting the reference signal with an impedance higher than an impedance with which each of the first drivers outputs the small-amplitude signal. The second transmission wiring is arranged between first and second power supply wirings corresponding to first and second potentials of the small-amplitude signal. The first and second potentials are supplied to each of the first drivers. The plurality of first transmission wirings are arranged close to each other, without being sandwiched between the first and second power supply wirings.
