Abstract
A solid state storage device includes a non-volatile memory and a controlling circuit. In a first read retry process, the controlling circuit judges whether an information corresponding to a first block of the non-volatile memory is recorded in the cache table. If the information is not recorded in the cache table, the controlling circuit sequentially provides plural predetermined retry read voltage sets to the non-volatile memory according to a sequence of the plural predetermined retry read voltage sets in the retry table and performs a read retry operation. If a read data of the first block is successfully decoded through the read retry operation according to a first predetermined retry read voltage set of the plural predetermined retry read voltage sets in the retry table, the controlling circuit records the first predetermined retry read voltage set into the cache table.
