NAND Flash控制器硬件设计与仿真验证

摘要

NAND Flash存储芯片的整体性能,在很大程度上会受到NAND Flash控制器的影响.为此在对NAND Flash的存储结构和接口进行仔细分析的基础上,设计了控制器的硬件功能,确定了各个命令执行时的设备状态转换关系,并在仿真环境下,利用NAND Flash控制器进行存储介质的读写及擦除等操作,全面验证了控制器的功能.结果表明,控制器工作正常,符合设计目标.%The performance of NAND Flash memory chips is largely affected by the NAND Flash controller.So the NAND Flash storage structure and interfaces are analyzed in this paper, then the functions of the controller are designed and each command transition in execution is described.All the operations, such as read and write, are executed via simulation to test the controller's functions.The results show that the controller works well and it meets with the design requirements.
