I am aware that it does not come close to DRAM, but it is faster than Flash, can be rewritten between thousands and tens of thousands of times more than Flash, and it is also byte-rewritable, unlike flash memory.
(I also specifically address some of the comparative issues in the talk.)
It is a significant step forwards. One of the problems with it is that current OSes can't really make good, efficient use of it.
That is what I am proposing a fix for – and one that should be relatively easy to implement.
