Product Description
SuperFlash is SST’s patented and proprietary NOR fl ash technology. SuperFlash technology has a number of distinct advantages for designing and manufacturing standalone fl ash and embedded fl ash products. SuperFlash technology is fully CMOS compatible and does not impact existing logic design rules and electrical parameters. This technology has been in high-volume production for more than sixteen years and is the non-volatile memory of choice for embedded applications.
