An integrated electrical module has a set of regular elements and a set of redundant elements, the elements being split over at least two blocks which are individually selectable by an input address and respectively containing regular elements and redundant elements. The integrated electrical module further has two repair circuits, each repair circuit being associated to a block, the two repair circuits being conditioned as a pair for a partner mode of operation, in which the addressing of an element from a first half-group of regular elements in the first block is diverted to a first half-group of elements in the second block and the addressing of an element from a second half-group of regular elements in the first block is diverted to a second half-group of elements in the second block.
