System and method for targeted efficient logging of memory failures

A method for logging memory errors, the method comprising:

• receiving, by an error logger of a memory controller of an information handling system, a first indication that a first memory event has occurred on one or more of the memory controller, a dual in-line memory module of the information handling system, and a memory channel that couples the memory controller to the DIMM;
• reading, by the error logger, first flag information from a first flag field of a first event block of a non-volatile memory device of the DIMM, wherein the non-volatile memory device is mapped to include a plurality of event blocks, each event block storing error information associated with memory events occurring on one or more of the memory controller, the DIMM, and the memory channel, and each event block including a flag field and a data field;
• determining, by the error logger, whether the first event block is locked based upon the first flag information;
• and
• if the first event block is not locked, then writing, by the error logger, second flag information to the first flag field and write event information to a first data field of the first event block, the event information to describe the first memory event.

An information handling system, comprising:

• a memory controller including an error logger;
• and
• a double data rate 5 (DDR5) dual in-line memory module (DIMM) coupled to the memory controller via a memory channel, the DDR5 DIMM including a non-volatile memory device mapped to include a plurality of event blocks, each event block to store error information associated with memory event occurring on one or more of the memory controller, the DIMM, and the memory channel, each event block including a flag field and a data field;
• wherein the error logger is configured to:
• receive a first indication that a first memory event has occurred;
• read first flag information from a first flag field of a first event block;
• determine whether the first event block is locked based upon the first flag information;
• and
• if the first event block is not locked, then write second flag information to the first flag field and write event information to a first data field of the first event block, the event information to describe the first memory event.
