What is a 3D NAND?

– The Memory Guy What is a 3D NAND? In the prior post we discussed the need to go vertically into the body of the die, since NAND flash can not be scaled much farther in length and width on the die’s surface. Toshiba invented a 3D NAND which has been adopted and refined by all flash makers.

Which companies are developing 3D NAND memory?

In addition, Micron, SK Hynix and Toshiba are also developing 3D NAND. In 3D NAND, the polysilicon strips are stretched, folded over and stood up vertically. Instead of using a traditional floating gate, 3D NAND uses charge trap technology. Based on silicon nitride films, charge-trap stores the charge on opposite sides of a memory.

How many stories can you build with 2D and 3D NAND?

We can add in as many stories to the building as we can physically manage, allowing ten, twenty, or fifty times as many people to live on the same amount of land that was previously so limited. So it is with 2D and 3D NAND.

What is 64-layer TLC 3D NAND?

If you’re designing a next-generation mobile user experience, Micron’s innovative 64-layer triple-level cell (TLC) 3D NAND technology solves the storage challenge. Offering designers a basic understanding of the features and benefits of each type of NAND Flash in order to select the proper device.
