Micron 128Gb TLC NAND Flash Chip Measuring 146mm²

Micron Technology, Inc. introduced the industry’s smallest 128Gb NAND flash memory device utilizing its 20nm process technology.

The new 128Gb device stores three bits of information per cell, called triple-level-cell (TLC), creating a compact storage solution.   

Measuring 146mm², the new 128Gb TLC device is more than 25% smaller than the same capacity of Micron’s 20nm MLC NAND device.

It is targeted at the cost-competitive removable storage market (flash cards and USB drives), which is projected to consume 35% of total NAND gigabytes in calendar 2013.1

Micron is now sampling the 128Gb TLC NAND device with select customers; it will be in production in calendar Q2.  

"This is the industry’s smallest, highest-capacity NAND flash memory device empowering a new class of consumer storage applications," said Glen Hawk, VP of Micron’s NAND solutions group. "Every day we learn of new and innovative use cases for flash storage, underpinning the excitement and opportunity for Micron. We are committed to enriching our portfolio of leading Flash storage solutions that serve our broad customer base."

Micron is presenting a paper on the 128Gb TLC NAND device at the upcoming International Solid-State Circuits Conference (ISSCC) on Feb. 19, in San Francisco, CA.
