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

michigan0 Sang Kim First, 28nm bulk is in volume manufacturing for several years by the major semiconductor companies but not 28nm FDSOI today yet. Why not? Simply because unlike 28nm bulk the LDD(Lightly Doped Drain) to minimize hot carrier generation can't be implemented in 28nm FDSOI. Furthermore, hot carrier reliability becomes worse with scaling, That is the major reason why 28nm FDSOI is not manufacturable today and will not be. Second, how can you suppress the leakage currents from such ultra short 7nm due to the short channel effects? How thin SOI thickness is required to prevent punch-through of un-dopped 7nm FDSOI? Possibly less than 4nm. Depositing such an ultra thin film less then 4nm filum uniformly and reliably over 12" wafers at the manufacturing line is extremely difficult or not even manufacturable. If not manufacturable, the 7nm FDSOI debate is over!Third, what happens when hot carriers are generated near the drain at normal operation of 7nm FDSOI? Electrons go to the positively biased drain with no harm but where the holes to go? The holes can't go to the substrate because of the thin BOX layer. Some holes may become trapped at the BOX layer causing Vt shift. However, the vast majority of holes drift through the the un-dopped SOI channel toward the N+Source,...
