ABSTRACT:
An apparatus for controlling an on die termination (ODT) includes a counting unit for receiving an external clock signal and a delay locked loop (DLL) clock signal, and counting the toggle number of each of external clock signal and the DLL clock signal from a preset number; a comparing control unit for comparing the counted toggle number of the external clock signal with that of the DLL clock signal in response to an ODT command signal, and outputting an ODT enable signal for controlling the ODT based on the compared result.
