Abstract: A data signal reception circuit output a binary level data signal by comparing the data signal with a reference potential in a reference potential storage unit. A data strobe signal reception circuit outputs a binary level data strobe signal by comparing one and the other of differential data strobe signals. A control circuit adjusts the reference potential by initial training, causes the reference potential storage unit to store the adjusted reference potential, and updates the reference potential in the reference potential storage unit based on an intermediate potential between one and the other of the differential data strobe signals at a time of the initial training and an intermediate potential between one and the other of the differential data strobe signals at a time of data reading.

Abstract: Provided is a semiconductor device with an output circuit in which a variation of a common voltage is suppressed in an idling mode and in a normal mode. The output circuit provided in the semiconductor device includes a first termination resistor and a second termination resistor and a drive circuit which flows current through the termination resistors. The output circuit is configured so as to be able to adjust the value of current which flows through the first termination resistor and the second termination resistor or the value of resistance of the first termination resistor and the second termination resistor.
