Abstract: The present invention is directed to memory systems. More specifically, embodiments of the present invention provide a memory system with a volatile memory, a persistent memory, and a controller. In a save operation, the controller copies contents of the volatile memory to the persistent memory as data units with their corresponding descriptor fields, where the descriptor fields include address information. In a restore operation, the controller copies data units from the persistent memory to their corresponding locations based on addresses stored at descriptor fields. There are other embodiments as well.
