3D Xpoint is all byte-addressable and byte-erasable, yes.

It is also available in DIMM form, called NVDIMMs, that plug directly
into the machine's memory bus and make it appear in the memory map.

Linux being Linux, however, the primary usage model is to partition
it, format it, and use it as a very very fast disk drive. :-(

I wrote the section of SUSE Linux Enterprise Server's documentation
concerning NVDIMMs. :-)
