Abstract
An integrated matrix memory includes standard sub-blocks and a redundant block. Each of the standard sub-blocks has a fixed number of standard sub-blocks, and the redundant block has one or more redundant sub-blocks. For addressing there is provided a detector for the address of a faulty standard sub-block. In that case a redundant sub-block is selected. Selection is realized by way of a sub-bus which forms part of the data path. Thus, a redundant system is achieved in which delay is minimized.
