1. A semiconductor apparatus comprising:
a global dock tree configured to drive a system dock signal to a complementary metal oxide semiconductor (CMOS) level to generate a first distribution dock signal and configured to drive the system dock signal to a current mode logic (CML) level to generate a second distribution dock signal;
a data output circuit configured to output data based on the first distribution dock signal; and
a data input circuit configured to receive the data based on the second distribution clock signal.
