Serial EEPROMs Answer Designers' Needs For More Point Storage

摘要

Traditional NOR- and NAND-type flash memories dominate most designer's minds when it comes to adding megabytes of nonvolatile storage to a system. But many cost-sensitive applications exist that don't need the high capacity or short access times they deliver. Filling the gap and providing a low-cost, small-format solution are bit-serial EEPROMs. These devices allow users to drop anywhere from a few dozen bits to 1 Mbit of nonvolatile storage into any system.
