Really this is a stepping stone before entering into the 3D era. This step will bring the ever required memory size increase per package as an in-between development before 3D fabrication techniques are ready for manufacturing ICs.
It may not be just cost but also the read current performance. The V-NAND could have a better read current than the smaller silicon channel, but its vertical channel direction could easily get in the way.
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.
