Scaling Limit

What is 3D NAND? Why do we need it? How do they make it?

3D NANDIn August 2013 Samsung announced its V-NAND, the first production 3D NAND, kicking off a big change in the way that NAND flash will be manufactured.  This new technology raises a number of important questions:

  • What exactly is a 3D NAND?
  • Why does the industry need to go to a 3D topology?
  • How the heck do they make such a product?

To answer these questions I assembled a series of articles posted as weekly segments on The Memory Guy blog during the fourth quarter of 2013.  The different sections are listed below, with hot links to each section.

Each of these is a topic that is complex enough to warrant its own post, so for the nine Fridays I published a post to explain each one in depth.  I hope you find it engaging and informative.

The End of Flash Scaling

The End is at Hand for NAND Flash ScalingEveryone knows that flash memory is about to hit its scaling limit – it’s right around the corner.  We’re ready for it because it’s been right around the corner for more than a decade now.  It’s so close we can taste it.

When will it happen?

One thing that is quite clear is that nobody knows when NAND flash will stop scaling.  Everyone knows that it’s soon, but researchers continue to find ways to push the technology another couple of process nodes past where anyone thought it could possibly go, and they have been doing this since Continue reading
