In the meantime, severe questions have arisen with respect to the physical validity of the memristor concept. When analyzed under the viewpoint of physics, the hypothetical state equations defining non-volatile memristors are by themselves in severe conflict with fundamentals of non-equilibrium thermodynamics. The critique can be found in “Fundamental Issues and Problems in the Realization of Memristors” by P. Meuffels and R. Soni (http://arxiv.org/abs/1207.7319) and “On the physical properties of memristive, memcapacitive, and meminductive systems” by M. Di Ventra and Y. V. Pershin (http://arxiv.org/abs/1302.7063).

If only my ’09 HP can last that long.

HP has implied that the delay is not technical, but rather one of profitability, since this technology will pretty much replace flash. However, I think memristors are turning out to be more of a challenge than they first believed, based on difficulties encountered by other groups working to perfect its implementation. I wouldn’t be surprised if they delay it again.

They DID say it would take 2.5 years of development to get it right…

The start of real technological evolution will be in 2015.

HP may well be out of business by the end of 2014. The company seems lost.

Hm, from what I’ve read, current memristor implementations still suffer from significant amounts of “noise,” which makes their data storage and processing prone to errors.
