Abstract: This paper researches the wear-leveling among chips when multi-bank writing on multi-bank flash storage architecture, propose an identification of hot data based on frequency of data access to solve the balanced distribution of frequently accessed data among multi-chips. Experimental results show that the identification methed of hot data based on frequency of data access is not only accurate for identifying hot data, but also appropriate for the hot data distribution among multi-chips.

Key words: Flash memory, multi-bank writing, identification of hot data

摘要： 在多路Flash存储结构基础上研究多路并行写入时各芯片间的磨损均衡问题。提出用基于数据访问频率的热数据判断方法解决频繁访问数据在各芯片之间的均衡分布问题。实验表明，基于数据访问频率的热数据判断方法，不仅能有效区分频繁和非频繁访问的数据，还能满足多芯片中热数据均衡分布的要求。
