Abstract
A semiconductor device having a fuse window above a substrate, the semiconductor device has at least one fuse protection circuit located under the fuse window. The fuse protection circuit includes a fuse having a first end connected to a first voltage and a second end. A first transistor having a drain is connected to the second end of the fuse, a gate for receiving an input signal, and a source is connected to a second voltage. A second transistor having a drain is connected to the second end of the fuse, a gate, and a source is connected to the second voltage. A first diode having an anode and a cathode, the anode of the first diode is connected to the second voltage and the cathode of the first diode is connected to the second end of the fuse.
