METHOD, CIRCUIT HAVING FUNCTION AND PROGRAM OF RESISTANCE VALUE COMPENSATIONS, AND METHOD AND PROGRAM OF CIRCUIT RESISTANCE VALUE TESTS

摘要

PROBLEM TO BE SOLVED: To provide a resistance compensating system of ODT circuit which is simple and high in accuracy.

SOLUTION: The resistance compensating system of compensating an ODT circuit 200 can realize a resistance value equivalent to a designated resistance value by combining a plurality of transistors, and is constituted in that a resistance value realized by selected transistors by selecting transistors to be combined in order is made to change in order.
