Abstract
The present invention relates to an apparatus for adjusting a slew rate of a data signal outputted by a signal from an external circuit in a semiconductor memory device and a method therefor. The apparatus includes: a slew rate control signal generation block for outputting a plurality of slew rate control signals through combining control codes inputted from the external circuit in response to a command signal; and a data buffer for adjusting a slew rate of a data signal inputted by using the slew rate control signals.
