Semiconductor device and method of operating the same

摘要

A semiconductor device includes 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 selectively outputting the training data input from the data storage through the global transmission lines or the DBI flag signal to a second channel.
