Toshiba -SanDisk take a beating

A little painful to see Micron and Samsung beating down Toshiba and SanDisk at this time, after their earlier statements. Maybe they'll come back with 10 nm.

Going vertical

I'd love to hear a simple explanation of what this vertical cell technology is all about.

For example, does it relate to FinFETs in some way?

Have a lot of respect for Samsung. It is indeed one of the best tech firms in the world today. They move in and they begin to dominate. Excellent piece of execution.

in the link they explain 3d nand. its more like building a skyscraper of nand cells than finfets.

That is a very good news for Samasung. It will be interesting to know cost, density and power advantage of this breakthorugh. Will this make future low cost laptop solidstate?

Assuming the 24 levels maximum, and a F=50 nm 6F^2 design rule, the maximum 3D density is equivalent to a conventional 12.5 nm floating gate. So the density lead for this case is temporary, until someone (if anyone) hits 10 nm floating gate. Increasing the number of levels or shrinking the 3D NAND design rule could increase costs when the number of steps starts multiplying, e.g., doubling.

Stacked 3d package for stacked NAND chips

Read in a blog somewhere that Samsung is going to sell their 3d NAND in a 128 GB configuration by stacking 8 chips vertically and connecting them with TSVs ( Through Silicon Vias ). Can Peter Clarke or anyone else comment on this ?

1)  I am slightly confused about the wordage "128 Gbit V-NAND" CTF:  Would that be the equivalent of 16GByte memory, or is this going to be a new unit of measure?

2) Does this news also mean that "Moore's Law" has been removed from its premature life support systems?

1) 1 byte = 8 bits so, yes, 128-Gbit = 16-Gbyte

It ihas been the convention within the semiconductor industry to quote memory capacity in bits. But either bits or bytes will do.

2) By which i mean planar scaling has become moot with regards to scaling memory capacity

I'll ask Samsung

LATEST ARCHIVED BROADCAST
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
