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.
Claims2
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, the method comprising the steps of:
- 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.
