What is 3D NAND? Why do we need it? How do they make it?
In 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?
Over the following nine weeks The Memory Guy will publish one post every Friday discussing each of these issues.
This post is the first of a series that will be posted in weekly segments through the fourth quarter on The Memory Guy blog. The different sections are listed below, with hot links added as each section is posted.
- Why Do We Need 3D NAND?
- What Is a 3D NAND?
- Making a Vertical NAND String
- An Alternative Kind of Vertical 3D NAND String
- How Do You Access the Control Gates?
- Benefits of Charge Traps over Floating Gates
- How Do You Erase and Program 3D NAND?
- 3D NAND’s Impact on the Equipment Market
- Who will make it and when?
Each of these is a topic that is complex enough to warrant its own post, so for the following nine Fridays I will publish a post to explain each one in depth. As each post is added, the bullet above will be converted to a hot link, so come back to this page to see each week’s installment.
