Abstract

A solid state storage device includes a control circuit and a non-volatile memory. The control circuit includes a retry table. In addition, plural retry read-voltage sets are recorded in the retry table, and the retry table is divided into plural retry sub-tables. The plural retry read-voltage sets are classified into plural groups. The plural retry read-voltage sets are recorded into the corresponding retry sub-tables. The non-volatile memory is connected with the control circuit. During a read retry process of a read cycle, the control circuit performs a hard decoding process according to a retry sub-table of the plural retry sub-tables. If the hard decoding process fails, the control circuit performs a soft decoding process according to another retry sub-table of the plural retry sub-tables.
