Abstract:
Provided is a semiconductor apparatus which includes a plurality of output buffers configured to connect a plurality of power sources, and a data noise measuring unit configured to fix an output data of a selected output buffer among the plurality of output buffers to have a specific level, measure a noise of the output data using a capacitance and control a slew rate of the plurality of output buffers based on the noise.
