SEMICONDUCTOR INTEGRATED CIRCUIT CAPABLE OF COMPENSATING TEMPERATURE VARIATION AND DRIVING METHOD THEREOF

摘要

PURPOSE: A semiconductor IC and a driving method thereof are provided to compensate the characteristic change of an output voltage by using an output code of a temperature sensor. CONSTITUTION: A temperature sensor(110) outputs a temperature code by detecting the temperature of the integrated circuit. A code converter(120) receives a predetermined ZQ calibration code and the temperature code. The code converter outputs an enable code by computing the ZQ calibration code and the temperature code. An output driver(130) receives an enable code. The output driver controls the driver strength according to the enable code value.
