NAND can't scale below the ONO thickness of 17-18 nm plus the silicon thickness of at least few nm. But that is where NAND is now. To go 3d to expand capacity has yield and ECC consequences which may offset the economic benefit.
I think, about a month back, we were discussing about the future of the NAND memories. Some believe that, the year 2011 is going to be the year of NAND memories. Is there any estimated time frame, by when the memories using newer technologies (such as MRAM, PCM etc.) are going to take place of the conventional memory technologies?
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.
