Assignee: NANYA TECHNOLOGY CORPORATION
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 7:
8. 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; and
dividing the predetermined voltage value by the subtracted current value to equal the fuse resistance of the at least one fuse element,
wherein the at least one fuse element comprises a plurality of fuse elements electrically connected to the CGND bus, the fuse elements are electrically connected to a plurality of transistor units respectively, each of the transistor units comprises one or more transistors connected in series, a fuse circuit comprising the CGND bus, the fuse elements and the transistor units, and the method further comprises:
setting the first condition indicating that a selected transistor unit of the transistor units operates in a linear region and remaining transistor units of the transistor units are turned off while the force voltage is applied to the CGND bus; and
setting the second condition indicating that the transistor units are turned off totally while the force voltage is applied to the CGND bus.
