摘要： 固体硬盘的出现改变了现有存储子系统的框架，也逐渐成为了嵌入式应用的主流存储设备。但是其自身的写机制由于需要先擦后写，成为了影响ssv性能的瓶颈。针对此问题，出于减少写操作次数这一思路提出了LRU-AI3算法，力图在基于Cache数据的访问频度上改进SSD置换算法。同时对现有算法进行了分析。

Abstract: The appearance of solid-state drive(SSl))incurs exciting changes in the architecture of computer storage sub-systems and SSD has become the main storage devices for embedded application, gradually. But the bottle neck problem of "erase before write" in NANI)based SSl)and its lifetime are the most important issues in today's SSl)design. This paper presented the algorithm,LRU-AB(access-based) by considering the access frequency to improve the performance of write operations. Meantime, we also discussed some existing algorithms for this area.
