摘　　要：介绍了一种高速同步存储系统的设计方案。系统使用NAND Flash构建片内存储阵列、同步管理技术和流水线的设计方案提高其存储速度。在Flash的同步模式下的读、写技术基础上,引入了片内Flash阵列管理方法,使整个Flash的存储速度有了大幅度的提高。同时针对Flash的坏块检测问题,引入了片外存储坏块地址的方法,提高了系统的坏快检测效率,保证系统的稳定性的同时,最大程度上提升了系统的性能。测试结果表明,该系统存储速度快、存储容量大、可靠性高。A high-speed synchronous storage system design is progresed. The system uses NAND Flash chip to build storage arrays,synchronization management technology and design of the pipe line to improve its speed. Based on read and write technology at Flash synchronous mode,a method of the Flash array management is introduced,so that the entire Flash memory speed has been greatly improved. While for the Flash bad block detection problem,the introduction of off-chip memory bad block address methods to improve the efficiency of the system to detect bad block ,ensures the stability of the system while improving the performance of the system to maximum extent. The test results show that the system exhibits its memory speed,large storage capacity and high reliability.
