Abstract
Provided is a method for reducing output data noise of a semiconductor apparatus which includes a plurality of output buffers to output data. The method includes the steps of: driving low data to a specific output buffer among the plurality of output buffers, and driving data transiting from a high level to a low level to the other output buffers; and measuring the magnitude of data noise occurring in output data of the specific output buffer, and deciding slew rates of the plurality of output buffers based on the measurement result.
