THE USE OF REDUNDANCY in memory components has gained increasing popularity in the last few years' >2,3. Laser fuse programming techniques have been employed t o replace defective elements in memory arrays4. These techniques have been used to improve yields on advanced technologies a t early stages of develop ment, as well as to reduce costs in volume memory production5. For the first time these techniques are used to achieve memory array bit counts on mature technologies. The approach we used enabled the des…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
