Abstract
A redundancy circuit for a semiconductor memory device utilizes a fuse ladder comprising alternating programmable resistive fuses and signal restorers connected to one another in series. The signal restorers coupled between the fuses prevent the formation of a high impedance resistive line with a floating node when one of the fuses in the ladder is blown.
