Re:Intel’s first Optane SSD: 375GB that you can also use as RAM

64 bit machines (given the right controllers etc) should be able to map the whole 375GB / 750GB directly into the memory space. You'd almost certainly need a kernel driver, similar to the way a graphics card is mapped into the address space but isn't treated as regular RAM. With the right driver you could just mmap() the address space.

Intel's strategy here is actually to continue using the standard NVMe interface for Optane SSDs, and to offer a hypervisor that does the job of presenting to the guest OS a pool of memory that is backed by a combination of DRAM and 3D XPoint.
