Abstract
A read table management method for a solid state storage device includes the following steps. If the lowest computation value in a hot group is lower than the highest computation value in a cold group when a read table adjusting process is enabled, a first read voltage set corresponding to the lowest computation value in the hot group and a second read voltage set corresponding to the highest computation value in the cold group are swapped with each other. Consequently, the second read voltage set becomes to belong to the hot group, and the first read voltage set becomes to belong to the cold group.
