A semiconductor device includes: a main driving unit configured to receive an output data and to drive the received data to a data output pad; a pre-emphasis data generation unit configured to compare a delayed data obtained by delaying the output data by one data period with the output data, to delay the comparison result by one data period, and to output the delayed data as pre-emphasis data; and a pre-emphasis driving unit configured to receive the pre-emphasis data and to drive the received data to the data output pad.
