PURPOSE: A semiconductor device is provided to secure signal integrity regardless of output driving performance by including a constant slew rate. CONSTITUTION: A mode register(50) outputs a driving performance first control signal. A pull-up slow rate controller(100) successively outputs output data and first to third delay output data. A pull-up free driver(200) outputs a plurality of pull-up control signals. A pull-down free driver(500) outputs a plurality of pull-down control signals. A pull-down slew rate controller(400) successively generates first to third delay pull-down data.
