Good question. Commodity DRAM and NAND are by far the majority of the memory market, and are used in PCs (DIMMs), servers (DIMMs), SSDs and smartphones. The first three are built into modules, the smartphone is an entire market onto itself. UFS is a memory subsystem, not really a memory? What about all the other markets and the memories that they require?
Mentioning HMC in the same article as commodity memory is odd, it is an embedded memory, and can't be built onto a module. There are lots of other memories for embedded applications worth mentioning.
New memory architectures combine nicely with the research into new filesystem architectures. Are these companies working with or at least tracking advances like ZFS? Both the Microsoft and the Linux / UNIX guys are doing some fairly sophisticated changes these days.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
