What Is 3d Nand Technology

Toshiba invented a 3d nand which has been adopted and refined by all flash makers.

What is 3d nand technology. So why hasnt 3d nand technology taken over the role of traditional planar nand. This is where planar nand single planes of nand cells are stacked vertically giving the v in v nand. The technology uses 3d charge trap flash ctf cells built in a pyramid or stair step edged structure with vertical channel holes or the more conventional floating gate mosfet technology. 3d nand is a next gen flash memory technology in which memory cells are stacked vertically to increase capacity providing much higher storage density and lower cost per gigabyte.

3d nand as the name implies involves cutting multiple layers into the silicon stacking memory cells to increase storage density. Rather than shrink the cells length and width why not turn the nand string so that its standing on its end. Flash storage like ssds is all the rage for pcs these days. 3d nand is a type of non volatile flash memory in which the memory cells are stacked vertically in multiple layers.

Compared to 2d nand 3d nand lowers costs reduces power consumption boosts reliability and provides higher data write performance. The design and fabrication of 3d nand memory is radically different than traditional 2d or planar nand in which the memory cells are arranged in a simple two dimensional matrix. It can be used in the same situations as traditional nand and has a number of advantages over hard disk and tape storage. And though the process isnt going as fast as we might hope for that storage is getting cheaper and denser all the time creeping up in value towards conventional spinning disk hard drives.

3d nand flash stacks memory cells vertically in multiple layers achieving a higher density than traditional nand memory. This concept is illustrated by this posts first graphic which was provided by applied materials. The idea is simple. By stacking cells in 32 layers we can reach much higher storage.

Transform the economics of storage with intel 3d nand technology built with floating gate architecture to expand ssd storage capacity and meet the demands of data centers professional and personal computing and embedded applications. The chips in question are vertically stacked in 36 48 72 or 64 and now 96 layers of flash cells. The biggest leap forward as of late has been 3d nand flash also known as vertical nand or v nand.
