Blowing past Toshiba/SanDisk

Given that Toshiba/SanDisk's 1Y generation stayed at 19-nm

http://www.eetimes.com/document.asp?doc_id=1280886

This looks likes a win for Intel/Micron planar HKMG memory cell structure.

But of course the proof is in the system-level pudding.

 

Does this put clear water between Micron and its competitors?

Glen Hawk emphasized the fact that this part is the smallest die size 128Gb NAND available much more than the 16nm process technology. But I agree that given the surprising move by SanDisk/Toshiba to stay at 19nm, Micron's migration down to 16 is impressive and differentiating.

Lets see what Samsung and Hynix can do?

Thanks guys for making me feel old! It seems like not that long ago that I was in the Boise Micron plant watching the boats of wafers float overhead and hearing the brags of the engineers that they were "sub micron".

But I am that old -- I can remember us repairing mask or design defects so we could test by "smushing" traces together or apart with a probe needle viewed through an optical microscope.

It's by QP? How is the die size compared to Samsung's TLC 128Gb NAND?

Tom Mariner:  You're not along, my friend.  I remember those days all too well.  I even remember when we talked about sub-micron as a futuristic goal!

With quadruple patterning? Figure they need to approach 10 nm to be more cost-effective.

@resistion- do you think they had to use quadruple patterning to make this part? I have not had any indication that that is the case. I can look into it.

It's pitch quartering by sidewall spacer processing, not four exposures. SK Hynix showed it as well at IEDM 2011.

Hopefully the SSD's will become much cheaper in the future.
