Abstract
A semiconductor memory device is provided. The device includes an on die termination circuit controlling a termination resistance value by detecting a phase change of a signal inputted through a pad. Additionally, the on die termination circuit changes the termination resistance value when an identical phase signal is inputted during n (n is positive integer) periods of a clock signal.
