Refresh seems to consume about 0.5W. The L4 latency is about half that of DDR channels, and the bandwidth about the same as 4 DDR4. Typical hit rate 95% (that would be remarkably good in general, but maybe the gamer market is what they aim at where locality might be better).
Not clear this is better than a Memory Cube. But probably much cheaper.
The DRAM will leak charge without a refresh, which requires power frequently every second. SRAM doesn't. Maybe SRAM doesn't sleep well enough anymore to conserve standby continuous power? What happened to near-threshold operation?
Interesting. The article only mentions "The eDRAM also required 1/5 of the keep-alive power compared with an SRAM device." Could you explain more about eDRAM's constant refresh and is that something that would be fixed someday, do you think?
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.
