Yep, and the reason 4DS is targeting high-volume high-density memory and *specifically* data centres and cloud computing is because on cost/benefit analysis it falls over for (i) embedded memory and (ii) stand-alone memory devices for the average consumer eg. USB sticks etc

Again, not everyone needs a Porsche to drive or needs an MBA to run a local fish n’ chip shop. For many it’s ‘overkill’. Cost will always govern ‘widest appeal’.

nb. Low-volume, low density ReRAM is still 1000 x faster than Flash, and WBT’s outperforms all new technologies at the lowest cost.

”Among all the current memory technologies, RRAM is attracting much attention since it is compatible with the conventional semi- conductor processes. Memristor-based RRAM is one of the most promising emerging memory technologies and has the potential of being a universal memory technology. It offers the potential for a cheap, simple memory that could compete across the whole spectrum of digital memories, from low-cost, low-performance applications up to universal memories capable of replacing all current market-leading technologies, such as hard disk drives, random-access memories, and Flash memories.”

”Although being a most promising memory element, critical issues for the future development of RRAM devices are reliable, such as data retention and memory endurance. A data retention time of over 10 years can be extrapolated from retention characteristics measured at high temperatures and a memory endurance of over [10 to the 6] cycles. Therefore, a statistical study of reliability, availability, and maintainability is essential for the future development of RRAM.”

Note from the first paragraph that low cost is a big deal?

In my opinion, 4DS can only (cost effectively) do memory for stuff like data centres and cloud computing

Opinion only, dyor etc
