Abstract:
E-fuses in an E-fuse memory array are programmed by applying a first programming pulse to a plurality of E-fuses to program the plurality of E-fuses to a first state; and then applying a second programming pulse to at least a selected E-fuse in the plurality of E-fuses to program the selected E-fuse to a second state.
