In a memory, faulty memory cells in a plurality of memory blocks are replaced by redundant memory cells. Each block comprises a plurality of first and second regular address lines with assigned memory cells and a plurality of first and second redundant address lines with assigned memory cells, through which the first and second regular address lines are replaceable. The first redundant address lines of a block are utilizable in at least one other memory block, faulty memory cells of the first redundant address lines displaced to another block being replaceable by second redundant address lines of the other block. According to the method for reconfiguring the memory, a fault image is determined and the memory is reconfigured so as to replace faulty memory cells. It is then determined whether at least one first redundant address line with faulty memory cells has been displaced from one block to another block by the reconfiguration. If one or more first redundant address lines with faulty memory cells have been displaced from one block to another block, the displaced first redundant address line with faulty memory cells is assigned to the other block. It is then determined whether the fault image is covered by the reconfiguration taking account of the assignment. If the fault image is covered, the reconfiguration is output as a valid solution.
