ABSTRACT:
When using a laser programmable fuse, a circuit should be 100% stable both before and after the fuse is blown. So far no CMOS circuit can be 100% stable without drawing a constant current. With the "Master fuse Enable" scheme one fuse circuit (master fuse) draws current while disabling all other fuse circuits on-chip. Thus giving 100% stability and reducing power consumption on a chip where no fusing has been done. If, however, one wished to use the rest of the fuses, then the master fuse is blown and all fuse circuits now become active and draw current.
