Abstract

The invention relates to a configuration for implementing redundancy for a memory chip, in which a fuse bank is connected to a comparator via a redundancy predecoder so that predecoded addresses can be compared with one another in the comparator and undecoded addresses can be stored in the fuse bank. This provides for a low-power and space-saving design.
