A semiconductor apparatus may include a first semiconductor chip; and a second semiconductor chip configured to transmit/receive signals to/from the first semiconductor chip. Further, a serializer/deserializer (SERDES) configured to serialize/deserialize input/output signals and a data bit inversion (DBI) logic electrically coupled to the SERDES and configured to perform a data inversion function on input/output data of the SERDES may be arranged in a preset region of any one of the first and second semiconductor chips.
