摘要： A method and circuit for implementing an eFuse sense amplifier, and a design structure on which the subject circuit resides are provided. A sensing circuit includes a pair of cross-coupled inverters, each formed by a pair of series connected P-channel field effect transistors (PFETs) and an N-channel field effect transistor (NFET). A first pull-up resistor is coupled between a positive voltage supply rail and a first sensing node of the sensing circuit. A second pull-up resistor is coupled between a positive voltage supply rail and a second sensing node of the sensing circuit. A first bitline is coupled to the first sensing node of the sensing circuit and a second bitline coupled to the second sensing node of the sensing circuit. One of a respective reference resistor and a respective eFuse cell is selectively coupled to the first bitline and the second bitline.

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.

摘要： A method implements effective testing of a sense amplifier for an eFuse without having to program or blow the eFuse. After initial processing of the sense amplifier, testing determines whether the sense amplifier can generate a valid “0” and “1” before programming the eFuse. A first precharge device and a second precharge device that normally respectively precharge a true sense node and a complement sense node to a high voltage are driven separately. For testing, one of the precharge devices is conditionally held off to insure the sense amplifier results in a “0” and “1”. This allows the testing of the sense amplifier devices as well as down stream connected devices. Once testing is complete, both precharge devices are controlled in tandem.
