Title:
オフチップドライバ制御用カウンタ回路およびこれを用いたオフチップドライバの出力電流値変更方法
Document Type and Number:
Japanese Patent JP4632920
Kind Code:
B2
Abstract:
Provided is a method of changing an output current value of an off-chip driver by means of a counting circuit including pluralities of fuses for controlling the off-chip driver, that includes measuring the output current value of the off-chip driver after completing a wafer test; cutting the fuses of the counting circuit off when the measured output current value is smaller than a target value, increasing the initial value of a off-chip driving control signal; and fabricating a package when the measured output current value is equal to a target value.
