Abstract: Performing an error recovery in response to determining an uncorrectable error in data stored in the memory system, storing the address of a memory location of the uncorrectable error in an address buffer and performing a recovery procedure for the processor core which may reset the processor core to a known status with correct data. When fetching data from a memory location and if it is determined that the address of this memory location is stored in the address buffer, moving the content of an entire cache line related to the address into a quarantine buffer of the processor core. When detecting an error in the data of the moved entire cache line, triggering a repair procedure for the data of this address which may be a special procedure to repair unrecoverable detected errors in data to be processed by a processor core.
