Design of a Reliable NAND Flash Software for Mobile Device

Flash memory in various embedded systems such as the backing memory is frequently used in an active type of RFID reader. Because batteries are used in a shifting environment and shifting is seriously considered, embedded systems receive a lot of influence by power failure while using and shock from outside environment. In order to manage efficiently flash memory, the use of flash file system is needed. When an error occurs, fast mounting and recovery are essential factors. This paper suggests appropriate constitution of NAND flash memory for fast mounting and recovery and also explains the way of recovery when a crash occurs. As the experiment is achieved in a light weight and in the optimized administrative environment system, efficiency can be quiet improved in the whole system
