From the abstract
"We exploit forming voltage variability coupled with a dedicated novel programming scheme to extract unique PUF signature"
This would appear to indicate that, while it may be a property of reram generally, it does require novel programming, which may correspond to a separate WBT patent???
Would be interesting to dig around to see if WBT and TSMC have different patents for this process ???
Sometimes there is more than one way to skin a cat as they say, (personal note: that's a weird expression).
