摘　　要：针对单片闪速存储器FLASH容量小、存储速度慢的缺点,提出一种利用FLASH实现大容量高速阵列存储系统的设计方案;根据FLASH存储器芯片结构特性,采用位扩展、并行总线及多通道流水线存储技术提高了存储容量与存储速度,并且实现了对存储阵列的无效块识别与有效块表的建立,在存储过程中各个模块对其有效块地址进行独立管理,保证存储系统的稳定性和高效性;通过试验验证按此方法实现的存储系统存储速度可达到64MB/s,存储容量能达到32GB,用相对小容量、低速的FLASH存储器构建了大容量高速阵列存储系统。This paper presents a design to achieve large-capacity high-speed FLASH array storage system by flash memory.Based on FLASH memory chip＇s configuration,we use bit extensions,parallel bus and multi-channel line technology to increase the storage capacity of memory and storage speed.Using a relatively small volume,low-speed FLASH memory constructed high-speed large-capacity FLASH array storage systems,and established the effective table to recognize invalid block and valid block.Each module manage the valid block address independent in the storage process to ensure that the storage system stability and efficiency.This method is verified by experiments stored in the storage system,to achieve speed of up to 64MB / s and 32GB storage capacity can reach.
