They should also be protected by ECC against field failures to achieve acceptable reliability. To avoid paying the area and power penalties of both approaches, we can use ECC to fix both fabrication and field failures. However, we show that efficient implementation of this approach may require special diagnosis hardware or new memory test algorithm that exhibit the so-called "single-read double-fault detection" property defined in this paper. We also propose test algorithms satisfying this property
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.
