Phase change memory, resistive RAM... what have they all got in common? That process called 'forming', i.e. zapping the device with a high voltage to create the conductive path, just like a lightning strike. Unless something remarkable has happened since the 1980's when I worked on this stuff, it never was reliable/manufacturable, and never will be.
I would be more than happy to be proven wrong by someone actually selling NVM using this technology, sadly all I see is research papers claiming that it's the 'next generation'.
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.
