Well, I guess this will be discussed sometime, so I thought may as well start a new topic before the other one gets completely derailed.
I was reading a little on it and it seems that already either I am confused, or the reporters are.
This page
http://www.crossbar-inc.com/technology/crossbar-overview.html states:
Crossbar RRAM technology is based on three simple layers:
•Non-metallic bottom electrode
•Amorphous silicon switching medium
•Metallic top electrode
then this video, linked from the previous page, says at around 0:18 "a bottom electrode, in this case, tungsten"
isnt tungsten a metal? And if the bottom layer is not metal, how can it be an electrode, or even conduct. I dont know what
TEM Visualisation means, I am guessing something like Thermal Electron Microscope. Maybe it is meant to be a demo of the process but not the Actual technology.
I never did physics or chem, so i guess that might have helped!!
I think this statement is ridiculous:
Secure Payments – Can permanently store the codes and encryption keys needed for secure applications such as large volume smart cards to high-end mobile processors for contactless payments.
May as well say "can permanently store Word documents" or "Can permantly store cute kitty pictures".
If it is a statement about anything to do with security - thats ridiculous, and jumping the gun a bit. I dont see any type of security there, it would have to be implemented in other additional components. If you can look at it through an electron microscpe, you can still see the bits, just the same as you can see programmed cells of eeproms.
The attack vectors are the same, there needs to be some kind of BUS, some kind of encryption..
SmartCards can already store the codes, maybe not permanently, but long enough to work for intended purpose.
