Abstract
A non-volatile flash fuse element and an array of such elements include fuses coupled to the input of a latch arranged as a differential comparator for constant current differential sensing. The fuse element includes a margining circuit that provides differential mass fuse margining. The margining circuit also allows the fuses to be stressed and screened. The fuse elements also provide constant current parallel programming.
