Given the empty description and single enable(1) value, this object most likely triggers the start of some form of memory-related logging on the card, inferred from its name pairing with the related cardMemLogLevel and cardMemClrLog objects nearby in the table. Because it has no documented description and sits alongside a log-level and a log-clear object, an admin would reasonably infer this begins recording memory events, such as allocations, errors, or usage snapshots, at whatever level cardMemLogLevel specifies, but should verify the exact behavior with vendor documentation before relying on it for production troubleshooting. For example, an admin sets cardMemStartLog to enable(1) alongside a configured cardMemLogLevel when investigating a suspected memory leak, then checks whether a retrievable log actually starts accumulating detail as a result.
