Abstract:
A method that includes evaluating, with a controller, local error detection (LED) information in response to a first memory access operation is disclosed. The LED information is evaluated per cache line segment of data associated with a rank of a memory. The method further includes determining an error in at least one of the cache line segments based on an error detection code and determining whether global error correction (GEC) data for a first cache line associated with the at least one cache line segment is stored in a GEC cache in the controller. The method also includes correcting the first cache line associated with the at least one cache line segment based on the GEC data retrieved from the GEC cache in the controller without accessing GEC data from a memory.
