PRETEC PCMCIA Linear Flash Card Series I conform to PCMCIA/JEIDA international standard and consist of multiple Intel’s 28F010 or 28F020 (or compatible) flash memory devices and decoder IC mounted on a very thin printed circuit board using surface mounting technology. Each card is organized as an array of individual memory segments. Each segment is 128K (or 256K) bytes in size. With this segment structure, the electrical segment-erasure capability gives the designer the flexibility to selectively rewrite segments of data while saving other segments for infrequently updated look-up tables.
