Micron VP remains upbeat on NAND future

Scaling thrives
In any event, there are still new and emerging applications for NAND. But there is no one-size-fits-all product, causing vendors to devise products for "specific markets," Shirley said.

There is still commodity NAND. Vendors are also devising products for the embedded, mobile and related markets. Micron also dropped hints about a NAND line designed specifically for the enterprise. Dubbed eNAND, the product is said to offer the reliability and error correction that is needed for the enterprise, according to Micron.

No details were given. In addition to the demand and applications picture, scaling continues for NAND, at least according to Micron. Still others believe NAND will hit the wall at the 2xnm node, prompting the need for a new type of so-called "universal memory."

At present, Micron and its NAND partner, Intel Corp., are shipping 34nm NAND. The companies just rolled out a 34nm, 3bit-per-cell line.

"The death of NAND is exaggerated," Shirley said. "We are seeing an incredible scaling path to the sub-20nm range."

By year's end, in fact, the Micron-Intel duo plans to ship a 2xnm NAND device. That device is somewhere between 25nm to 30nm. In the lab, the two companies have devised a device in the low-20nm range, he said, adding that a 1xnm product is viable.
