减轻读干扰的垃圾回收算法
A Garbage Collection Algorithm of Reducing Read Disturb
摘要
Abstract
NAND flash memory is widely used in various application scenarios due to its many characteristics,such as mobile phones,tablet computers and so on,but flash memory also has two characteristics of concern:service life and data reliability.In the using process of flash memory,the influence of read disturb on data accuracy will increase with time.Therefore,by studying the influence caused by read disturb,a garbage collection algorithm FRT-GC(Frequency and Read Times-Garbage Collection)that can reduce the influence caused by read disturb is proposed.This algorithm starts garbage collection at the right time by counting the usage times and frequency of each flash memory block,and minimizes the influence caused by read disturb.The experiments show that the algorithm has a good effect in reducing read disturb.关键词
