摘要： A design structure for electrically programmable fuse sense circuit having an electrically programmable fuse and a reference resistance. A first current source is coupled, through a first switch, to the electrically programmable fuse. A second current source is coupled, through a second switch, to the reference resistance. A precharge signal enables the first current source, the second current source and closes the first switch and the second switch, creating voltage drops across the electrically programmable fuse and the reference resistance. When the precharge signal goes inactive, the first current source and the second current source are shut off, and, at the same time the first switch and the second switch are opened. A latching circuit uses a difference in the voltage drops when the precharge signal goes inactive to store a state of the electrically programmable fuse, indicative of whether the electrically programmable fuse is blown or unblown.

摘要： A method and circuit for implementing eFuse resistance screening, and a design structure on which the subject circuit resides are provided. An eFuse is sensed using a first reference resistor. Responsive to the eFuse being sensed as blown with the first reference resistor, the eFuse is sensed using a second reference resistor having a higher resistance than the first reference resistor. Responsive to the eFuse being sensed as unblown with the second reference resistor, the eFuse is recorded as poorly blown. Reliability concerns are identified quickly and accurately without being required to measure the resistance of the eFuse.
