Abstract
A terminal resistance adjusting method adjusts a terminating resistance within a semiconductor integrated circuit. The method includes obtaining a comparison result by comparing a reference voltage and a voltage of a first node that is coupled to a first voltage via a current supply circuit, the first voltage being one of a power supply voltage and a ground voltage, controlling a monitoring resistor part which has a plurality of first resistors when making a calibration, so as to selectively couple the first resistors in parallel between the first node and a second voltage based on the comparison result, the second voltage being the other of the power supply voltage and the ground voltage, and controlling a terminating resistor part which has a plurality of second resistors when controlling the terminating resistance of the terminating part, so as to selectively couple the second resistors in parallel between a second node and the second voltage based on the comparison result similarly to the first resistors of the monitoring resistor part.
