Abstract: In one embodiment, an apparatus comprises a memory device controller toreceive a command comprising an identification of a region of data stored in a memory and a request to change a location of the region of data. The memory device controller is further to request the modification of at least one entry of a plurality of entries, the plurality of entries to map an externally addressable address space of the memory to a physical address space of the memory, the modification of the at least one entry to change a mapping of the region of data between the externally addressable address space and the physical address space without moving the region of data within the memory.

Abstract: Examples may include a non-volatile memory having a memory including a first table of device physical addresses and a second table of physical device addresses; a control register to receive a clone command to clone a second memory region of the memory as a copy of a first memory region of the memory, the first and second memory regions being referenced by different device physical addresses; and address translation logic, upon receipt of the clone command, create a first entry in the first table for each page of the first memory region and create a second entry in the first table for each page of the second memory region, each first table entry for the first memory region and each first table entry for the second memory region pointing to a same entry in the second table.
