高速大容量固态存储器设计

摘要

To satisfy high-rate mass-capacity data recording, a novelty record device is introduced by the paper based on FLASH. The method to operate FLASH array and the skill about high-rate record are described. Based on Universal Serial Bus(USB) and FPGA technique, several FLASH slices work together controlled by FPGA to complete high-rate mass-capacity. The design utilizes module method and pipelining technology. Simulation result shows that the system can achieve data recording speed of 80 MB/s, data playback speed of 20 MB/s, storage capacity of 256 GB.%为满足信息的高速大容量存储需求,提出基于闪存(FLASH)的固态存储器设计方法.介绍FLASH的结构、存储操作的实现方法和高速存储等相关技术.以通用串行总线和现场可编程门阵列(FPGA)可编程设计为基础,通过FPGA对多片FLASH的编程控制实现高速大容量存储.仿真结果证明,该方法能实现80 MB/s的数据记录速度和20 MB/s的数据回放速度,以及256 GB的存储容量.
