i could be wrong.. but i think what hes saying is if it starts at half the cost of DRAM (16gb for 100$ for ddr4? so 16gb NRAM for 100$) then hopefully it will drop more to SSD pricing eventually (250gb for 100$)
either way this is great and im excited!
Ah, yes, I could see that, except I think you have your numbers wrong

If 16GiB DRAM is $100 and this NRAM is half, it would be $50 for 16GiB NRAM.. but yeah, its quite a bit more than what we pay for SSD drives for sure.. Your post, and my giant cup of coffee made that pretty clear!
So yeah, as a high activity hot-swap type disk, a smaller disk with 1000+X endurance and less power for same performance would still be valuable in enterprise, but not so much for normal home use where SSD endurance is less of a problem currently, but storage space IS important.
Definitely exciting, and perhaps we won't have to wait too long to learn more: "some are already developing 28nm 3D designs that enable "multi-GB" products that are denser than DRAM. Nantero indicated that its partners will announce these products soon."
If mechanical disk and SSD paired to make hybrids, perhaps we'll see hybrid SSD+NRAM in the next few years as well? Done correctly, you could probably achieve higher reliability/endurance on an SSD if you had e.g. 32GiB of NRAM to use for data that changes frequently, and the SSD is more of an archival dump.
