>By contrast, 3D XPoint works by changing the properties of the material that makes up its memory cells to either having a high resistance to electricity to represent a one or a low resistance to represent a zero.
Which sounds a lot like memristors: https://en.wikipedia.org/wiki/Memristor to me. If it's memristor memory, the main advantages are that it's cheap, uses hugely less power than flash, takes up less space, and has far lower latencies.
We're probably a long ways from replacing DRAM with memristors because it's still much higher latency, but if this stuff scales up well you could do something like put the whole page file on it and get even faster loads than current top of the line SSDs.
The press release seems to be intentionally silent on the actual memory cell technology. Another possible tech the cell might be based upon is some variant of Nano-RAM.
