ABSTRACT:
A multiple-time electrical fuse programming circuit is described. The circuit includes a programming counter to record the number of programmings, a blowing reference voltage generator to generate a blowing voltage reference wherein the fuse resistance after programming is determined by the blowing voltage reference, at least one self-controlled programmable fuses which includes a programmable fuse and a control circuit. The multiple-time electrical fuse programming circuit also has a fuse detection reference generator and a high voltage power source.
