Frankly I do not know what you are referring to. I would never promote a memory that dies at 100 Cand the data I sent to EEttimes goes to 300. Currently it is 400 C.
Now the self saturating is another story. The relationship between compliance and on currenyy can saturate at low compliance values, that is also In the literature. Of filaments
In one of your papers, there was a model of the insulator state. I am not sure if that model is updated yet. It suggested self-saturating current (which I presume not correct). More seriously, it also showed that the resistance of the insulator would be dramatically decreased at an elevated temperature above 100 C. Is there an update to this in an upcoming publication?
