The is a Serial Peripheral Interface SPI Flash Memory with SST proprietary, high-performance CMOS SuperFlash technology. The SST25VF020B devices are enhanced with improved operating frequency and even lower power consumption. The split-gate cell design and thick-oxide tunnelling injector attain better reliability and manufacturability compared with alternate approaches. The SST25VF020B devices significantly improve performance and reliability, while lowering power consumption. The devices write Program or Erase with a single power supply of 2.7 to 3.6V for SST25VF020B. The total energy consumed is a function of the applied voltage, current and time of application. Since for any given voltage range, the SuperFlash technology uses less current to program and has a shorter erase time, the total energy consumed during any Erase or Program operation is less than alternative flash memory technologies.
