Abstract: 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…
