Abstract
A semiconductor device includes an impedance control signal generation unit configured to generate an impedance control signal for controlling an impedance value, a first processing unit configured to process the impedance control signal in response to a first setup value and generate a first process signal, a first clock termination unit configured to be coupled with a first clock path and determine an impedance value responding to the impedance control signal, and a second clock termination unit configured to be coupled with a second clock path and determine an impedance value responding to the first process signal.
