Abstract

Disclosed is a method of recording the type and quantity of errors caused by a memory DIMM, within a storage device mounted to the DIMM. This will prevent defective DIMM's from being used if inserted into another DIMM socket. If errors exceed a given quality level, the Operating System can indicate on that DIMM that it is defective and take's that DIMM off-line to prevent problems with the programs that are running in that system. Even if the DIMM is removed from the system, a record of the defect stay's with that DIMM.

On Part Memory DIMM Error Logging

   Disclosed is a method of recording the type and quantity
of errors caused by a memory DIMM, within a storage device mounted
to the DIMM.  This will prevent defective DIMM's from being used if
inserted into another DIMM socket.  If errors exceed a given quality
level, the Operating System can indicate on that DIMM that it is
defective and take's that DIMM off-line to prevent problems with the
programs that are running in that system.  Even if the DIMM is
removed from the system, a record of the defect stay's with that
DIMM.

   This idea expands on the concept of recording detected
memory DIMM errors somewhere assessable to the system user so that
marginal or defective DIMMs can be disabled and then replaced when
convenient.  In computer systems, the ability to detect hardware
errors in memory has been available for many years.  Recently
disclosed is the process for collecting memory errors and storing
them in a format in which the computer system user could identify
which memory DIMM sockets contain defective DIMMs.  The problem with
this concept is that there is no connection between the DIMM error
data stored in the system and the defective DIMM.

   The advantage of logging errors onto the memory DIMM is
that the record of the error stays with the DIMM that caused the
error.  This means that if a defective DIMM is placed into another
DIMM socket or even placed into another system, the record of the
defect is permanently asso...
