Watermarked ReRAM: A Technique to Prevent Counterfeit Memory Chips. (arXiv:2204.02104v1 [cs.CR])

Electronic counterfeiting is a longstanding problem with adverse long-term
effects for many sectors, remaining on the rise. This article presents a novel
low-cost technique to embed watermarking in devices with resistive-RAM (ReRAM)
by manipulating its analog physical characteristics through switching
(set/reset) operation to prevent counterfeiting. We develop a system-level
framework to control memory cells' physical properties for imprinting
irreversible watermarks into commercial ReRAMs that will be retrieved by
sensing the changes in cells' physical properties. Experimental results show
that our …
