20 nanometer manufacturing processes, you say? We say pshaw, be gone luddite. Sandisk and Toshiba just announced the latest product from their joint venture: a 19nm 64Gb (8GB) X2 memory chip; aka, the smallest NAND flash memory chip in the world. At least it will be when it hits production in the second half of the year. They are, however, sampling the monolithic chip this quarter in case you're interested in stacking a batch of 16 into an ultra-high density 128GB SSD. Anyone?

SANDISK ANNOUNCES 19-NANOMETER MANUFACTURING TECHNOLOGY-WORLD'S SMALLEST, MOST ADVANCED PROCESS NODE

Industry-leading 19nm 64-gigabit X2 memory chip; smallest NAND flash memory chip in the world
Volume production scheduled for the second half of 2011

Milpitas, California, April 20, 2011 - SanDisk Corporation (NASDAQ: SNDK), the global leader in flash memory cards, today announced a 64-gigabit (Gb), 2-bits-per-cell (X2) based monolithic chip made on 19-nanometer (nm) technology, the most advanced memory process technology node in the world. This latest technology enables SanDisk to produce embedded and removable storage devices with the high capacities and small form factors used in mobile phones, tablet computers and other devices.

SanDisk will sample its 19nm 64Gb X2 device this quarter and expects to begin high-volume production in the second half of 2011. At that time, SanDisk will also add 3-bits-per-cell (X3) products fabricated with the 19nm process technology to its product lineup.

"We are excited to introduce the world's smallest and lowest-cost NAND flash chips based on industry-leading 19nm process technology in our ongoing collaboration with our manufacturing partner Toshiba," said Yoram Cedar, executive vice president and chief technology officer, SanDisk. "Products based on this technology are designed to enable new applications, form factors and consumer experience that will continue to drive the flash industry to new heights."

The 19nm memory die uses the most sophisticated flash memory technology node to date, including advanced process innovations and cell-design solutions. SanDisk's All-Bit-Line (ABL) architecture with proprietary programming algorithms and multi-level data storage management schemes help yield multi-level cell (MLC) NAND flash memory chips that do not sacrifice performance or reliability.
