A semiconductor device is provided to stably output a data by increasing a slew rate of an output driver according to an increase of temperature. A semiconductor device includes a temperature information output part(310), a pre-driver(320), and a main driver(330). The temperature information output part outputs temperature information(TEMPA,TEMPB,TEMPC) inside the semiconductor device. The pre-driver generates one or more driving signals(UP-PRE,DN-PRE) according to a logic level of an output data. An initial slew rate of the driving signal is determined by a test mode signal. The pre-driver changes the slew rate of the driving signal according to the temperature information inside the semiconductor device. The main driver outputs data in response to the driving signal. A slew rate of the output data of the main driver is changed according to a change of a slew rate of the driving signal. |
