Abstract

An integrated memory has a normal bit line for transferring data from or to normal memory cells connected to it, and also a normal sense amplifier, which is connected via a line to the normal bit line and connected to a data line and amplifies data read from the normal memory cells. Furthermore, the memory has a redundant sense amplifier for replacing the normal sense amplifier in the redundancy situation. The redundant sense amplifier is likewise connected on the one hand to the line and on the other hand to the data line and, in the redundancy situation, serves for amplifying the data read from the normal memory cells. A method for repairing an integrated memory is also provided.
