A method of utilizing DRAM which may contain defective memory locations. The invention describes a method and two algorithms. In a data processing system a processor will make requests to a memory using logical addresses. A translator is used to determine what physical address in the memory device corresponds to a logical address. In the general methodology, a set of logical addresses is assigned corresponding to physical memory locations. The memory device is then mapped to determine which memory locations are defective. The invention outlines a method where a defective physical address that corresponds to a logical address is swapped with a non-defective physical address. The advantages of the invention include not needing redundant memory, fuses, a time consuming burn-in procedure, and allowing the device to repair memory locations that might become defective during the operation of the device.
