ABSTRACT:
There is provided a semiconductor device that includes: an output buffer capable of adjusting an impedance based on an impedance adjustment signal, and a through-rate control circuit that adjusts a through rate of the output buffer based on at least the impedance adjustment signal, wherein the through-rate control circuit sets a relatively high through rate when the impedance adjustment signal designates a relatively low impedance, and sets a relatively low through rate when the impedance adjustment signal designates a relatively high impedance.
