Abstract:Conventionally, Static Random Access Memory (SRAM) failures rely on memory bitmap for failure analysis. Static fault localization approach is ineffective except if the defect is large enough to cause a resistive short between the VDD and VSS nodes. However, it was observed that subtle defects that fall in the wordline (WL) of the pass gate transistor results in a partially turned-on NMOS with electroluminescence that can be effectively localized by Photon Emission Microscopy (PEM). In this paper, we leverage o… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
