Fuse programming schemes for robust yield

An apparatus comprising:

• a program circuit coupled to a fuse to generate first and second currents to program the fuse, the second current is higher than the first current, the program circuit comprising one or more devices to generate the first and second currents;
• and
• a control circuit coupled to the program circuit to control generating the first and second currents in succession;
• wherein the control circuit comprises:
• a program enable generator coupled to the one or more devices to assert a program enable signal to the one or more devices a first time to generate the first current and a second time after the first time to generate the second current;
• and
• a variable supply generator coupled to a fuse program terminal of the fuse to generate first and second fuse program voltages at first and second times, respectively, the second fuse program voltage being higher than the first fuse program voltage.

A system comprising:

• a front end processing unit to receive and transmit a radio frequency (RF) signal, the RF signal being converted to digital data;
• a digital signal processor (DSP) coupled to the front end processing unit to process the digital data;
• and
• a programmable logic device coupled to the DSP to perform logic functions, the DSP having a plurality of fuses and an in system programming (ISP) circuit, the ISP circuit comprising:
• a program circuit coupled to a fuse to generate first and second currents to program the fuse, the second current is higher than the first current, and
• a control circuit coupled to the program circuit to control generating the first and second currents in succession.
