A variety of applications can include systems and/or methods of partial save of memory in an apparatus such as a non-volatile dual in-line memory module. In various embodiments, a set of control registers of a non-volatile dual in-line memory module can be configured to contain an identification of a portion of dynamic random-access memory of the non-volatile dual in-line memory module from which to back up content to non-volatile memory of the non-volatile dual in-line memory module. Registers of the set of control registers may also be allotted to contain an amount of content to transfer from the dynamic random-access memory content to the non-volatile memory. Additional apparatus, systems, and methods are disclosed.
