US Patent 11631472 Built-in memory repair with repair code compression

In a described example, an integrated circuit (IC) includes a repairable memory system. A repair controller is coupled to the repairable memory system. The repair controller includes compression logic configured to encode memory repair code data for a respective instance of the repairable memory system and provide compressed repair data. A non-volatile memory controller is coupled to the repair controller and to non-volatile memory. The non-volatile memory controller is configured to transfer the compressed repair data to the non-volatile memory for storage.
