Abstract
According to one exemplary embodiment, a programmable poly fuse includes a P type resistive poly segment forming a P-N junction with an adjacent N type resistive poly segment. The programmable poly fuse further includes a P side silicided poly line contiguous with the P type resistive poly segment and coupled to a P side terminal of the poly fuse. The programmable poly fuse further includes an N side silicided poly line contiguous with the N type resistive poly segment and coupled to an N side terminal of the poly fuse. During a normal operating mode, a voltage less than or equal to approximately 2.5 volts is applied to the N side terminal of the programmable poly fuse. A voltage higher than approximately 3.5 volts is required at the N side terminal of the poly fuse to break down the P-N junction.
