The memristor terminology is probably for PR. Defects, especially charge trapping type, lend themselves to memory effects pretty easily, and nothing is ever defect free, so a lot of these defect-driven memories can appear under the right stress conditions.

Charge trapping models for resistance switching would be open to objections which apply to all models which do not involve stable atomic/ionic rearrangements, i.e., phase changes, in localized regions of the considered materials: the memory states last for several years without decay, and it is hard to see that non-equilibrium charge distributions could exist for so long in thin-film devices.

I believe A.Sceptic's issue is not with "Hynix and other companies" but rather with those who write memristor papers and are either not aware of the physics issues or have made no real attempt to incorporate the actual physics into dynamic systems models (regardless of whether it is called a "memristor" or not). The lead HP memristor scientist (Stan Williams) has publically stated in an earlier EETimes article that HP's memristor research is "essentially complete" and any delay is for business reasons blamed on Hynix. However, to my knowledge, there is no realistic model from HP or anyone else incorporating the known physics into a dynamic systems model (regardless of whether you call it a memristor or not). The lack of accurate physics models will make product design difficult and Hynix's engineers will likely need to rely on trial and error for manufacture. This will likely make it more costly and time consuming to manufacture "memristors".

That is how they should have to know could be done for knowing the real one to know. - BrandStar Entertainment
