ABSTRACT:
A slew-rate adjusting apparatus for use in a semiconductor memory device includes: a slew-rate modulation signal generator for generating a slew-rate modulation signal according to the number of control codes having a first logic level among a plurality of control codes, which are programmable at an exterior; and a pre-driver for adjusting a slew rate of a data signal by changing the number of switching elements turned on in response to the slew-rate modulation signal.
