Patent ID: 11906560
Assignee: NANYA TECHNOLOGY CORPORATION
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A system of measuring a fuse resistance, and the system comprising:
a storage device configured to store a predetermined voltage value of a force voltage on a common ground (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; and
a processor electrically connected to the storage device and configured to access and execute the at least one instruction for:
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 of a plurality of 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.
