Abstract
An exemplary embodiment includes a method of controlling a semiconductor device. The semiconductor device includes a memory cell array including a plurality of memory cells connected between a plurality of word lines and a plurality of bit lines, a row decoder for receiving a row address and selecting a word line corresponding to the row address, a column decoder for receiving a column address and selecting a bit line corresponding to the column address, a sense amplifier for reading data stored in a memory cell connected to the selected word line and the selected bit line, and a data output driver. The method includes setting a calibration code for a driver control code, to control an initial current strength of the data output driver, and changing the calibration code to change the driver control code during a read or write operation for the memory cell array.
