Abstract

本申请公开了一种数据处理方法，包括：获取闪存块的第一读干扰计数值；若第一读干扰计数值不大于第一门限且属于调整区间，则获取统计信息，统计信息是根据第一集合得到的，其中包括闪存块中多个目标数据单元对应的多个原始出错比特数，每个目标数据单元对应一个原始出错比特数；根据统计信息判断第一读干扰计数值是否满足调整条件；若满足，则根据统计信息确定闪存块的第二读干扰计数值；若第二读干扰计数值大于第一门限，则对闪存块进行数据迁移。本申请还提供相应的装置和存储介质。本申请技术方案能够提升读干扰计数值评价闪存块所受读干扰影响程度的准确度，还可以在满足数据可靠性的同时，避免不必要的GC操作，提升存储器的使用寿命。
