Claim 13:
14. A non-transitory computer readable medium to store a plurality of instructions for commanding a computer to execute a method of measuring a fuse resistance, and the method comprising steps of:
preloading a predetermined voltage value of a force voltage on a CGND bus electrically connected to at least one fuse element, a first current value of a measured current through the CGND bus in a first condition, a second current value of another measured current through the CGND bus in a second condition, and at least one instruction;
subtracting the second current value from the first current value, so as to get a subtracted current value, thereby removing a value of a leakage current through the CGND bus;
dividing the predetermined voltage value by the subtracted current value to equal the fuse resistance of the at least one fuse element;
setting the first condition indicating that a selected transistor unit operates in a linear region and remaining transistor units are turned off while a first voltage of various voltages is applied to the CGND bus;
setting the second condition indicating that the selected transistor unit operates in the linear region and the remaining transistor units are turned off while a second voltage of the various voltages is applied to the CGND bus, and the second voltage is subtracted from the first voltage to equal the predetermined voltage value; and
choosing the first current value and the second current value from various current values related to the various voltages according to the first condition and the second condition before subtracting the second current value from the first current value,
wherein the step of dividing the predetermined voltage value by the subtracted current value comprises: dividing the predetermined voltage value by the subtracted current value to equal the fuse resistance of a selected fuse element.
