A method for handling errors in a cache memory without processor core recovery includes receiving a fetch request for data from a processor and simultaneously transmitting fetched data and a parity matching the parity of the fetched data to the processor. The fetched data is received from a higher-level cache into a low level cache of the processor. Upon determining that the fetched data failed an error check indicating that the fetched data is corrupted, the method includes requesting an execution pipeline to discontinue processing and flush its contents, and initiating a clean up sequence, which includes sending an invalidation request to the low level cache causing the low level cache to remove lines associated with the corrupted data, and requesting the execution pipeline to restart. The execution pipeline accesses a copy of the requested data from a higher-level storage location.
