PURPOSE: A semiconductor IC is provided to improve the stability and the accuracy of data input/output control by generating a DBI(Data Bus Inversion) flag signal using a data bus inversion function. CONSTITUTION: A DBI flag generating unit(110) generates a DBI flag signal by using a plurality of output data sets. A data inversion unit inverses a plurality of output data sets according to the DBI flag signal. The data inversion unit(120) transmits a plurality of output data sets to a global transmission line. A data output unit(130~200) outputs a plurality of output data sets transmitted through the global transmission line through a pad. An inversion circuit unit inverses and outputs a plurality of output data sets according to the DBI flag signal in a timing due to the input/output strobe signal.
