Claim Text:
1. A semiconductor device comprising: a data storage suitable for storing a training data for a training operation; a data bus inversion (DBI) calculator suitable for calculating DBI information for the training data input from the data storage through global transmission lines, generating a DBI flag signal based on the DBI information and outputting a DBI data, which is the training data inverted according to the DBI flag signal, in response to a DBI signal; a first multiplexer suitable for selectively outputting the training data input from the data storage through the global transmission lines or the DBI data to a first channel in response to a training signal and the DBI signal; and a second multiplexer suitable for selecting between outputting the training data input from the data storage through the global transmission lines and the DBI flag signal to a second channel in response to the training signal.
