Abstract

An information handling system includes a memory controller with an error logger, and a DIMM coupled to the memory controller via a memory channel. The DIMM includes a non-volatile memory device mapped to include event blocks that store error information associated with memory events occurring the memory controller, the DIMM, and the memory channel. Each event block includes a flag field and a data field. The error logger receives an indication that a memory event has occurred, reads first flag information from a flag field of an event block, determines whether the event block is locked based upon the first flag information, and if the event block is not locked, then writes second flag information to the flag field and writes event information to a data field of the event block. The event information describes the memory event.
