Abstract
An integrated memory is described that has memory blocks with column lines and row lines as well as at least one redundancy row line for replacing in each case one of the row lines in any of the memory blocks. In addition, each memory and memory block has a deactivation unit for deactivating the memory block. The integrated memory has deactivation lines, each of which is connected to an input of the deactivation unit of one of the memory blocks. Each memory block has a deactivation decoder that is connected at the output end to all the deactivation lines. If one of the row lines of a first memory block of the memory blocks is replaced by a redundancy row line of a second memory block of the memory blocks, the deactivation decoder of the second memory block deactivates the first memory block via the corresponding deactivation line.
