ABSTRACT:
A first passive ESD protection device for an electronic component in a microcircuit includes a fuse element shunting the component to be protected and includes a passive programming path from the outside of the microcircuit to the fuse element. A second passive ESD protection device is deactivatable and reactivatable and includes a first fuse element shunted by a second fuse element in series with a first antifuse element. Shunting the second fuse element with a third fuse element in series with a second antifuse element permits a second deactivation and reactivation to be performed. Additional deactivation/reactivation cycles may be permitted by providing additional series combinations of fuse elements and antifuse elements shunting the preceding fuse element. Combinations of the passive protection device and dual elements comprise ESD protection schemes which may be deactivated and activated multiple times.
