Abstract
A redundancy circuit for semiconductor memories having word lines organized in segments. If a defective word line appears in a segment then, by virtue of inter-segment redundancy, a redundant word line in the same or in a different segment can be activated by a segment select signal. Fuse sets assigned to the respective segments provide output signals. The segment select signal is generated directly by evaluating the fuse set output signals.
