FIVE-VOLT ONLY OPERATION is now an industry standard for electrically erasable and programmable nonvolatile memories.A 4K nonvolatile static RAM (NVRAM) with on-chip high-voltage generation and regulation was designed with high density and future scalability as key design parameters. Using wafer stepper HMOs I dual poly FLOTOX' technology and a restructured cell, a die size of 30,268 mils2 (19.53mm2) was achieved: Figure 1. Single pulses control the data transfers: STORE (static RAM t o E2PROM) and RECALL (EQ…
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.
