Abstract:
1. A semiconductor device comprising: a plurality of first receivers, each operating at a first operation voltage, receiving a single-ended input signal having a small amplitude, and having a function of sensing the single-ended input signal; a plurality of first drivers, each operating at a second operation voltage lower than the first operation voltage and outputting the single-ended input signal having a first voltage difference with a first impedance value; a plurality of first transmission wirings, each having a first length corresponding to a distance between one of the first drivers and one of the first receivers and transmitting the single-ended input signal; a common reference signal inputted to each of the plurality of first receivers; a second driver operating at the second operation voltage and outputting the reference signal with a second impedance value higher than the first impedance value; a second transmission wiring having at least the first length and transmitting the reference signal; and first and second internal power supply generation circuits, relating to the second operation voltage, generating high- and low-side potentials of the single-ended input signal, respectively, supplying the potentials to each of the plurality of first drivers, and outputting the potentials to first and second power supply wirings having at least the first length, respectively, wherein the second transmission wiring is arranged between the first and second power supply wirings, without the plurality of first transmission wirings being arranged between the first and second power supply wirings, and wherein the plurality of first transmission wirings are arranged close to each other, without being sandwiched between the first and second power supply wirings.
