"What I don't think we have seen yet is a DRAM card plugging into the PCIe bus."
Actually this has been shipping by DDRdrive LLC since 2006, the DDRdrive X1 is a DRAM based PCIe card with an equal capacity of on-board NAND and a SuperCap PowerPack to provide the back-up power after a host power loss.
The market opportunities for DRAM based PCIe are obviously not as broad as Flash based PCIe today, but the inherent random write limitations of Flash relative to DRAM has yet to be overcome. For those capacity constrained applications bound by random write IOPS, such as the ZFS Intent Log (ZIL), a DRAM based PCIe solution is a perfect match.
Memory storage density are pushing the technology boundary because the price is such a delicate tipping point that companies can save millions on a small price difference. The explosion of the data storage and devices has and will spur the demand.
I would look forward to a realistic cost assessment of 3D memories, with vertical NAND being the prime example, particularly how much area is added that is NOT stacked. Apparently, that was a big deal observation for Samsung's second generation V-NAND when it released its SSD based on it.
Regarding silicon proof of new memory technology, again it should be assessed whether Mb-scale silicon should be sufficient, since that costs much less (1000x less) than Gb-scale.
My Architecture session (B-11/B-12)all day on Tuesday at this conference will include a SanDisk talk on "Data Shaping" for sub-20nm NAND, NVM Express (based on PCIe) talks from LSI/Avago and Fastor Systems, and a talk by FMS 2013 Best of Show winner NVMdurance on their patented endurance techniques. At Tutorial T-4 on Wednesday: learn about M.2, an easy way to bypass SATA by connecting directly to PCIe.
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.
