Abstract
An on-die termination circuit including: a DQS circuit block configured to terminate a DQS pad in response to a first impedance adjustment signal which is transmitted through a global line; and a DQ circuit block configured to terminate a DQ pad in response to a second impedance adjustment signal which is generated by changing the first impedance adjustment signal or a value of the first impedance adjustment signal depending on whether a setup operation proceeds.
