Memory Module Tracking

This disclosure is related to memory module tracking, addressing issues such as counterfeit. Shown in Figure 1 is the basic arrangement of the DIMM plugged into a standard socket containing various components such as a circuit terminal, movable clip, serial EEPROM, power switch, miniature battery, electrical connection traces, and external power. Some of the key parameters that are being disclosed are the module insertion and removal tracking process along with addressing the counterfeit memory module detection technique (see Figures 2, 3, 4, and 5 below).

Reliable operation of memory module connector:

Server memory subsystem presents numerous challenges, and ensuring reliable operation of memory modules is one such challenge.

DIMM connector ensures proper interface of memory module and right level of electrical contact to support high-speed bus operation.

Insertion and removal of DIMM modules in a connector often has an adverse impact on the electrical connectivity as plug cycle increases.

Maintenance and field service upgrades (during fault conditions) require DIMM modules replacement.

In manufacturing test, characterization and qualification processes, there is a need for DIMM insertion and removal with an object to limit plug count.

Connectors have a limited number of insertion and removal limits ensure reliable operation. However, there are no mechanisms that exist today as part of the connector to support this tracking.

Currently, co...
