The split gate cell design and thick oxide tunneling injector attain better reliability and manufacturability compared with alternate approaches. The SST39SF020 device writes (Program or Erase) with a 5.0V-only power supply. The SST39SF020 device conforms to JEDEC standard pinouts for x8 memories. Featuring high performance byte program, the SST39SF020 device provides a maximum byte-program time of 30 µsec. T...
