Gen 9 powerwise: how will it be?

Universal Memory is right around the corner, next year there is a company that will begin production of this tech and it's basically an SSD that can be used like RAM, fast access comparable to GDDR5, with all the benefits of big storage, so capacity by 2018/19 will be ridiculously huge compared to what it is now, forget 128GB, we're talking Terabytes worth of accessible memory, even if the platform holders limit how much is useable by devs they could easily have 512GBs just for game use, not that they'd need it, but he options will be there.

But then like SSD's, this new memory will deteroirate in the same way? In that entire blocks have to be erased every time you write something to it, even if that data is smaller than the block size. And the more you keep erasing and writing, it starts to deteriorate and becomes slower, or even unusuable.
SSD's work well for harddrives when you only use them for the operative system and apps, and don't constantly save other smaller files on it. But I can imagine that as RAM it would be quite busy performing a lot of erasing and writing all the time.
Haven't read about this, but that makes me wonder how viable this will be.

Crossbar's RRAM is apparently 10X better than NAND for endurance, although with further development Crossbar says it's possible to achieve 100X that, while it's a long ways off of DRAM, it's a lot better than the current best SSD technologies. Apparently it can be made in the same facilities as NAND is currently and Crossbar has already secured $50M in funding and are apparently only one stage away from production.

As for the way it writes I think it's a lot more specific, not dealt with in blocks, it's Byte addressable.

Here's a link to a recent article about the technology:
