Design and Realization of Large Capability NAND FLASH in ARM Embedded System

With the quickly development of embedded system,FLASH storage becomes the key to manage the huge amounts of data efficiently.Through a detailed instance of NAND FLASH KFLASH9F2808U0C of Samsung Corporation,this article introduces the basal structure of NAND FLASH,and introduces a design and realization of NAND FLASH in the ARM embedded system based on the demand of embedded system and the character of NAND FLASH storage.This design has been proved on μC/OSII operation system,and the result testified that the design fits the request.
