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.
