摘要
A plurality of flash memory wordlines of a flash storage device are divided into a plurality of wordline groups based on read error counts associated with the wordlines and a plurality of read level offsets. Each wordline group is associated with one of a plurality of read level offsets determined while dividing the plurality of flash memory wordlines, and associations between the plurality of read level offsets and the plurality of wordline groups are stored for use in connection with read levels to read the flash memory wordlines of the respective wordline groups.
