A system that includes a non-volatile memory subsystem having non-volatile memory. The system also includes a plurality of memory modules that are separate from the non-volatile memory subsystem. Each memory module can include a plurality of random access memory packages where each first random access memory package includes a primary data port and a backup data port. Each memory module can include a storage interface circuit coupled to the backup data ports of the random access memory packages. The storage interface circuit offloads data from the memory module in the event of a power loss by receiving data from the backup data ports of the random access memory packages and transmitting the data to the non-volatile memory subsystem.
