Toshiba is saying they will be making 15nm chips. http://www.businesswire.com/news/home/20140422006898/en/Toshiba-Starts-Mass- Production-Worlds-15nm-NAND#.U1zyeeY5TKw
Toshiba has achieved the world's smallest class chip size with the 15 nm process plus improved peripheral circuitry technology. The new chips achieve the same write speed as chips formed with second generation 19 nm process technology, but boost the data transfer rate to 533 megabits a second, 1.3 times faster, by employing a high speed interface.
Toshiba is now applying the 15nm process technology tp 3-bit-per-cell chips, and aims to start mass production in the first quarter of this fiscal year. The company will develop controllers for embedded NAND flash memory in parallel and introduce 3-bit-per-cell products for smartphones and tablets, and will subsequently extend application to notebook PCs by developing a controller compliant with solid state drives (SSD).
How are they doing this? What are the implications for ST?
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
