1. A method, comprising: dynamically managing, by a memory module controller of a memory module, storage of operational state data into an extended random access memory, the extended random access memory including random access memory in the memory module and random access memory in a host device, the operational state data for operating the memory module controller; and determining, by the memory module controller in association with a wake up from a shut down state or from a sleep state of the memory module, whether to read at least some of the operational state data from the random access memory in the host device, the determining being based at least on a transmission, from the host device, indicating that the random access memory in the host device is compromised.
