Abstract
This paper introduces the structure,the functions and the basic operating principle of Nand-Flash based on the ARM embedded μClinux system.The specialties of Nand-Flash and embedded system are taken into account,it designs a solution for larger-capacity NAND Flash application on embedded system.Meanwhile it provides the circuit of hardware interface and the implementation of software driver programming.Based on Nand-Flash’s files system,it then implements the management of data and storage room efficiently.The effect is proved to be well in practice.
