Abstract
A semiconductor system may include a first semiconductor device and a second semiconductor device. The first semiconductor device may output a training entry signal and a transmission signal. The second semiconductor device may generate selection codes and a control signal in response to the training entry signal. The second semiconductor device may adjust a level of a reference voltage signal for buffering the transmission signal in response to the selection codes and control a capacitance of an internal node. The reference voltage signal may be outputted from the internal node in response to the control signal.
