3D NAND technology: What it is and where it's headed

Editor's note

3D NAND flash stacks memory cells vertically in multiple layers, achieving a higher density than traditional NAND memory. It can be used in the same situations as traditional NAND and has a number of advantages over hard disk and tape storage. So, why hasn't 3D NAND technology taken over the role of traditional, planar NAND?

The last few years have been tumultuous for NAND flash. Last year, a lengthy NAND flash shortage drove up SSD costs and slowed the transition to 3D NAND technology. 3D NAND is a denser, faster option than traditional NAND, but high manufacturing costs and complexity have extended the transition from older NAND technology. The precise chip manufacturing process of 3D NAND requires a substantial investment from vendors and can make production a lengthy and delayed process.

Luckily, the shortage has ended, and the technology appears to be thriving. Vendor investment and interest have paid off, with a number of flash memory companies announcing NAND flash products and expressing enthusiasm for the future of 3D NAND. The question now appears to be less about whether an organization should consider 3D NAND, but where does it work best?

In this guide, we'll take a look at the best applications for 3D NAND, the intricacies of NAND flash technology and what's available. We'll also examine the future of 3D NAND and what role it will play in the data center of tomorrow. If you're new to 3D NAND technology, take a look at our glossary at the end of the guide for a quick introduction to some key terms.
