I suppose you all know that WD CTO came from HP, so he has the best perspective on the 3D ReRAM supposedly being developed for SCM. What he says is here: https://www.theregister.co.uk/2017/03/09/martin_fink_speaks/

"This will take time. It is a journey. I fully expect us to see initial use cases for SCM that do in fact add a layer to storage/memory hierarchy. That's OK. It's part of the learning and discovery cycle."

"As an industry, we all are working toward SCM and we'll all make progress in different ways. But there's really nothing too controversial about any of it."

"SCM would allow us to have extremely high-density connections to processors. But, today, processor vendors limit the physical connections, or how much memory can be attached." (It's pin-limited)

Yes, at FMS last year the WD CTO pitched his ReRAM as better than 3DXP but not ready until 2018-2020. We shall see. Intel got out early but might have left people stung by inflated expectations.

It would be great to have another 3D option, and I would certainly welcome it. My skepticism comes from three reasons.

1) ISSCC 2013 paper not so impressive

2) Few years ago approached for collaboration, they didn't seem serious. Asking about it more recently, they still seem that way.

3) HP involvement also questionable

On their public roadmap last year in Dec, WD had 3D ReRAM in second half of 2018. Assuming that's start of production, they should ship in 2019. If the timing has changed since, no idea. Intel announced XPoint as ready when they knew it's not even close to ready but wouldn't expect that kind of behavior from WD/Toshiba.

Does their 3D ReRAM even work? I doubt it. Are they even allowed to access the 3D XPoint or MRAM? That is another set of issues.

@realjjj  At last year's Flash Memory Summit the former Marvell CTO gave a great talk on a memory agnostic NVM controller for SCM. He told me afterward it was a few years ahead of the SCMs ;-(

I think there was a Dilbert cartoon with a theme like this! Managers demanding you be innovative typically does not work. Get the mangement out of the process and perhaps you will come up with some innovative ideas! Most companies will never put up with that as it leaves the power struture vulnerable.

"The hard drive market is flattening and declining slightly over time"

That's a very unrealistic view. The hard part is yet to start for HDDs. PCs will decline faster and faster going forward (on foldable displays in mobile and later on glasses) while NAND attach rates in PC and console are relatively low and can only improve.

Worst case scenario, China breaks through in NAND, the market enters a state of permanent oversupply around year 2020 and NAND pricing becomes very favorable. At that point HDDs are dead in consumer (PC, CE, branded) and the only application fit for them is cold storage - even that would only last for a few more years.

 

Would have been interesting to ask him about SCM, Marvell seems the right partner for Western Digital in developing controllers for WD's 3D ReRAM.
