Data receiving device, a semiconductor apparatus, and a semiconductor system using the data receiving device

A data receiving device comprising:

• a clock receiver configured to generate a plurality of internal clock signals from a clock signal and a complementary clock signal based on a switching enable signal;
• and
• a plurality of data receivers configured to receive data and a reference voltage and configured to compare the data and the reference voltage in synchronization with the plurality of internal clock signals, respectively, to generate a plurality of internal data,
• wherein, among the plurality of data receivers, a data receiver receiving an internal clock signal, of which a logic level transitions signals when a logic level of the switching enable signal transitions, changes a voltage level of the reference voltage when the logic level of the switching enable signal transitions.

A semiconductor apparatus comprising:

• a strobe receiving circuit configured to generate a first internal strobe signal and a second internal strobe signal from a data strobe signal and a complementary data strobe signal based on a switching enable signal;
• a first data receiver configured to compare data with a reference voltage in synchronization with the first internal strobe signal to generate first internal data;
• and
• a second data receiver configured to compare the data with the reference voltage in synchronization with the second internal strobe signal to generate second internal data and configured to compensate for a voltage level change of the reference voltage based on the switching enable signal.
