That's interesting how you divide it
you specified types of semiconductor memory but you left out details of magnetic media evolution
NAND, RRAM, etc. is just evolution of semiconductor memory
The same as perpendicular magnetic recording and HAMR is evolution of magnetic media

Oh yeh, I should have just said semiconductor, magnetic, and optical.

I could have drilled down into the types of oxides and other techniques. but...

No, I am totally 100% correct every single time I am right.

seems actually Terabytes:



here I was crapping on about commercialization and the years it will take:


Emailing ACE now for a price on the PC-3K-RRAM, hope it is under a Mil..

Promises, promises ...

Elpida unveils ReRAM prototype (25th January 2012):
http://www.bit-tech.net/news/hardware/2 ... rototype/1

"While not yet ready for commercialisation, Elpida has promised that it will continue developing ReRAM technology in partnership with NEDO, Sharp, the National Institute of Advanced Industrial Science and Technology (AIST,) and the University of Tokyo with a view to producing gigabit-class ReRAM modules in volume using a 30nm process by 2013."

Samsung reports trillion-cycle ReRAM (7/13/2011):

HP, Hynix to launch memristor memory 2013 (10/6/2011):
http://www.eetimes.com/document.asp?doc_id=1260374

"[Hewlett-Packard] have a lot of big plans for [memristor two-terminal non-volatile memory technology] and we're working with Hynix Semiconductor to launch a replacement for flash in the summer of 2013 and also to address the solid-state drive market..."

Panasonic first with mass-produced ReRAM computer (31st July 2013):
http://www.bit-tech.net/news/hardware/2 ... ic-reram/1

"Before you get too excited, however, it's worth checking the specifications of the MN101LR devices. Designed for embedded use, the systems are eight-bit microcomputers running at 10MHz with just a few kilobytes of ReRAM available to the user. The target market, Panasonic explains, is low-complexity systems such as battery-powered healthcare products, security systems, automotive and sensor devices."

Low complexity, maybe, but the applications are mission critical.

Yes but even then from what I have read the Memory will be more complimentary to systems than a replacement for NAND. mainly expense of production will keep it to the richer customers that need performance and things like video cards.
I don't even know if we NEED to increase tech at the moment. The main reason for this stuff increasing is bigger storage, but I rarely see a UFD or mem card over 32GB that has used even half capacity. mostly photos anyway, that no-one looks at again, or TV shows/videos that can be redownloaded or streamed.. nothing like recovering a flash drive to find 20GB of Glee

I can't wait for this new technology to become mainstream. ISTM that domestic consumers are crying out for reliability more so than speed or capacity. AFAICT, NAND flash has already hit its limits, so the time is ripe for something to finally replace it. I wonder how soon before Samsung, Crossbar et al announce their own products.

If 3D XPoint can dispense with wear levelling, then ISTM that SSDs should become more reliable and less complex. I imagine that chip-off recoveries will become a lot simpler. No more reassembly of FTL jigsaw puzzles, just read the memory chips in address order like normal RAM.

As for HDDs, as marvellous as they are, I hope I live to see the end of them.

if they can get the speed up around DRAM, then you can do away with the current

Disk<-->Ram<-->CPU<-->RAM<-->Disk

and instead have

Mem<-->CPU<-->Mem

OS's would need to be re-written from scratch, Motherboards would need to be redesigned.. A lot else has to happen aside from just starting to churn out chips.



As Franc said, domestic users aren't worried about speed, they want reliability.. Pity the products that are given to domestic users are not based on what we cry out for. It has started to be developed 5 - 10 years ago, then given to major enterprise that can pay the massive amounts for the cutting edge tech because they NEED the speed/storage/whatever at any cost.. and this gets to a point where the consumers start to be able to afford it as quantity sold drives down cost, bugs are fleshed out etc.

I don't think in the future we are going to see new tech take as long to get to market as previously.

I hope that your theory of simpler memory is true Franc, but alongside of this tech is the human side.. driving privacy and encryption. Nothing halts a data recovery job quicker than some well implemented encryption.

as for storage benefits and performance.. ever since I started playing Duke Nukem 3D, computers and video card technology has kept to a common theme.. I call it the Full Res Theory, it is kind of like moores law..

Whatever the very latest game tech is... the performance it needs(gfx card, cpu, ram) is such that I wont be able to afford that rig for another 1 or 2 game tech cycles.

Examples, barring memory lapse of old fart, is something like:
when Doom came out, I could play Duke on my PC full Res
when Unreal Tournament came out, I could play Doom on my PC full Res
When Half-Life came out I could pay Unreal full Res

I mean they had to add GPU processing in web browsers to try and at least use SOME of the beasts we take for granted these days. whats coming.. 16k textures and 1TB games?...

I like the idea of Memory<--> CPU <---> Memory interaction. But it means the death of Windows as we know it.

Without volatile memory how will you recover when it BSOD's out on you?

Better have a good backup plan.
