It's very difficult for a non-volatile memory to attempt the speed typical of SRAM or DRAM. Basically some barrier is needed to preserve a state and this barrier would naturally limit switching speed unless using higher voltages. Furthermore, being a series resistance, the MRAM should dominate the resistance yet not load the circuit so much. On the other hand, keeping this resistance load low would prevent scaling.
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.
