ABSTRACT:
Method and apparatus for accessing a memory, wherein the memory has a cell array having a number of memory cells arranged in cell array elements. A cell array element determined to be defective is deactivate. After the cell array element is deactivated, an address of a cell array element is applied to an activation apparatus of the memory in order to activate the cell array element for a given memory access. The applied address is compared with stored error addresses which are assigned to defective cell array elements. In the event of a match between the applied address and one of the error addresses, a redundant cell array element is activated instead of the cell array element.
