A memory module determines that the memory module is connected to a memory module connector. The memory module receives the connector ID from the connector and communicates, to the connector, a memory module ID associated with the memory module. A connector-module ID token is generated using the connector ID and the memory module ID. It is determined that the connector-module ID token was not received from the connector within a predetermined time window. Data on the memory module is erased in response to not receiving the connector-module ID.
