Method and device improving SSD read-retry efficiency and computer device

The invention relates to a method and device for improving SSD read-retry efficiency and a computer device. The method comprises classifying word lines in an erasing unit according to different positions.; obtaining a effective retry level value and storing the effective retry level value. Through classification of the word lines inside the erasing unit according to different positions, the distribution similarity of the retry level is refined to the word line level. When the retry level value of the word line at a certain position is effective, the memory cells on other word lines in the sameerase cell can refer to the effective retry level value, the accuracy is high, the efficiency of reading and retrying is improved, and the overall reading performance of the solid state disk is improved. 本发明涉及提升SSD读重试效率的方法、装置及计算机设备，该方法包括将擦除单元内部的字线根据不同位置进行分类；获取生效的重试等级值，并存储生效的重试等级值。本发明通过将擦除单元内部的字线根据不同位置进行分类，将重试等级的分布相似性细化至字线级别，当某个位置字线的重试等级值生效时，同类擦除单元里其它字线上的存储单元可参考该有效重试等级值，准确率高，提高了读重试的效率，提升固态硬盘的整体读性能。
