DIMM device controller supervisor

摘要

The various implementations described herein include systems, methods and/or devices used to enable performing supervisory functions for a dual in-line memory module (DIMM), at a controller in the DIMM. The method includes upon power-up, determining a power supply voltage provided to the DIMM. In accordance with a determination that power supply criteria are satisfied, the method includes: (1) performing one or more power-up operations, including initiating a usage counter, (2) monitoring a temperature of the DIMM, (3) monitoring the DIMM for occurrence of one or more of a set of predetermined trigger events, and (4) in response to detecting one of the set of predetermined trigger events, logging information corresponding to the detected predetermined event.

1. A method of performing supervisory functions for a dual in-line memory module (DIMM), at a controller in the DIMM, comprising:
upon power-up, determining a power supply voltage provided to the DIMM; in accordance with a determination that power supply criteria are satisfied, the power supply criteria including a requirement that a power supply voltage provided to the DIMM falls within one of N predefined voltage ranges, wherein N is an integer greater than one:
performing one or more power-up operations, including initiating a usage counter;monitoring a temperature of the DIMM;monitoring the DIMM for occurrence of one or more of a set of predetermined trigger events,
wherein the set of predetermined trigger events is selected from the group consisting of a temperature measurement of the DIMM in excess of a predefined temperature and a current number of program-erase cycles performed on respective flash memory that meets predefined criteria; andin response to detecting one of the set of predetermined trigger events, logging information corresponding to the detected trigger event, wherein the logging includes storing the logged information in non-volatile memory in the DIMM.
