MILPITAS, Calif, Feb. 22, 2012 - SanDisk Corporation (NASDAQ: SNDK), a global leader in flash memory storage solutions, today announced it has developed the world's smallest 128 gigabit (Gb)* NAND flash memory chip currently in production. The semiconductor device can store 128 billion individual bits of information on a single silicon die 170mm2 in size - a little more than a quarter of an inch squared, or smaller than the area covered by a U.S. penny.
At 19nm, SanDisk is deploying its ninth generation of multi-level cell (MLC) NAND products and fifth generation of X3 technology. This combination of manufacturing and technical expertise helps SanDisk pack more information into each memory cell making it possible to create a smaller, denser NAND flash memory chip.
"Building a 128Gb NAND flash memory chip with this level of complexity is an incredible achievement," said Mehrdad Mofidi, vice president, Memory Design. "This innovation allows SanDisk to continue to be a leader in helping our customers deliver smaller, more powerful products capable of doing more at lower cost."
In addition to reduced size, the 128Gb semiconductor device has an industry-leading X3 write performance of 18 megabytes (MB)** per second. This level of performance is achieved using SanDisk's patented advanced all bit line (ABL) architecture and means that X3 technology could be extended to certain product categories that use MLC NAND flash memory. A technical paper outlining the breakthrough will be presented at the International Solid-State Circuits Conference (ISSCC) in San Francisco today.
The 128Gb NAND flash memory chip was developed jointly by teams from SanDisk and Toshiba at SanDisk's Milpitas campus. The effort was led by Yan Li, director of Memory Design at SanDisk. Products based on the 128Gb three-bit per cell technology began shipping late last year and have already started to ramp into high volume production. SanDisk has also developed a derivative product based on the success of the 128Gb chip - a 64Gb, X3 NAND flash memory chip that is compatible with the industry-standard microSD™ format. The company has also started to ramp production of this additional chip technology.
NAND flash memory is the technology behind the high reliability, small form factor storage solutions that SanDisk sells to OEM customers for use in a wide variety of products such as smartphones, tablets and Ultrabooks. It is also the technology used in products SanDisk sells through its retail channel in the form of imaging and mobile cards, USB drives and mp3 players.
