Claim Text:
1. A semiconductor device comprising: a data bus inversion (DBI) decision unit suitable for deciding whether a DBI operation mode is performed, based on a read data, and generating a DBI decision signal corresponding to a result of the decision; an output control unit suitable for generating an arrangement control signal in which a delay amount of time for the decision is reflected, during a DBI operation mode; a data synchronization unit suitable for synchronizing the read data with the arrangement control signal and output the synchronized read data and inverted signals of the synchronized read data, during the DBI operation mode; and a data output unit suitable for receiving the synchronized read data, the inverted signals of the synchronized read data, the arrangement control signal and an output control signal, and selectively outputting the synchronized read data and the inverted signals of the synchronized read data, to an external in response to the DBI decision signal, the arrangement control signal and the output control signal, during the DBI operation mode.
