ABSTRACT:
An electrically blowable fuse circuit having a fuse which may be placed in a condition to be blown. The circuit includes a first transistor having a body, a source, a drain, and a gate. The source is connected to one end of the fuse and the drain is connected to ground. The first transistor further includes a controllable parasitic device in its body. A second transistor is connected to the parasitic device such that when the second transistor is turned on, the parasitic device turns on the first transistor, allowing the fuse to be blown when the fuse is placed in a condition to be blown.
