Micron launches dense 128-Gbit NAND flash

LONDON – Micron Technology Inc. (Boise, Idaho) has launched a triple-level cell (TLC) 128-Gbit NAND flash memory in a 20-nm manufacturing process technology that it claims is the world's densest memory.
At 146 square millimeters the memory die is more than 25 percent smaller than the company's same-capacity MLC NAND memory and it is intended for use in removable storage, including flash memory cards and USB drives. On the assumption of reasonable process yield a small die area results in more memories per wafer, lower costs for the manufacturer and lower prices for the buyer.
Micron expects removable storage to consume 35 percent of NAND memory in 2013. The 128-Gbit NAND is sampling with selected customers and will be in volume production in the second quarter of 2013, Micron said.
No details of the read or write performance, or the cycling endurance of the memory were provided by Micron in a press release but a paper is due to be presented on the 128-Gbit TLC NAND device at the upcoming International Solid-State Circuits Conference (ISSCC) on Feb. 19 at 3:15pm, in San Francisco, California.
16-Gbytes of storage required four die at 34-nm and two die at 25-nm. Micron claims an area saving of 25 percent at 20-nm over the previous generation.

Amazing, everything you own digitally can be stored on one chip (unless you are hording more bits than you will ever use)...When do we expect to see 1 Terabit memory?

Its 128Gbit ie 16Gbyte Too less to fit in my data .. I probably have 50GB of Songs/Videos alone.

iniewski, apparently you and I have very different data collections. I recently had to switch from a 1.5 Terabyte hard drive for backup to a 3.0 Terabyte hard drive because my data wouldn't fit on the 1.5 Terabyte drive.

So they seek to overtake SanDisk 19 nm 128 Gb using TLC. This year will 16 nm happen?

Well, the takeaway message from Micron's paper seems to be don't do TLC at 20 nm and don't scale any lower.

resistion, can you elaborate further on that? It would seem to be an odd thing to question the product reliability at a conference while released the product at the same time.

I agree it's odd but the paper presents that way. Maybe the TLC reliability is as expected. Still, didn't even get any ECC assurance. I assume there will be or this is for really error-tolerant products. The FG interference curve was also presented ominously enough.
