The DBI determination unit is configured to determine whether to perform DBI based on first data on a main data line and configured to generate DBI data. The first inverter is configured to invert or non-invert the first data according to the DBI data to generate second data. The CRC calculation unit is configured to generate CRC data based on the second data and the DBI data. The second inverter is configured to invert or non-invert the first data according to the DBI data to generate third data.
