Abstract
An apparatus for adjusting a resistance value of a driver of a semiconductor integrated circuit in which the resistance value of the driver is adjusted according to a code signal. The apparatus includes a control means that generates a plurality of counting mode signals such that the unit of counting is changed in a predetermined period, a counting means that counts the code signal in the unit of counting that is changed in response to the plurality of counting mode signals, according to a count up/down signal, and a comparing means that compares a voltage obtained by converting the code signal with a reference voltage to generate the count up/down signal.
