Summary:PROBLEM TO BE SOLVED: To provide an apparatus for adjusting the resistance value of a driver of a semiconductor integrated circuit that is capable of performing quick adjustment and is capable of widening an adjustable range of the resistance value. SOLUTION: The apparatus is provided for adjusting the resistance value of the driver of a semiconductor 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 units of counting that is changed, according to the plurality of counting mode signals, according to a count up/down signal, and a comparing means that compares the voltage, obtained by converting the code signal with a reference voltage and generates the count up/down signal.
