  • Publication number: 20160077914
    Abstract: An error correction method for a solid state storage device is provided. A controller of the solid state storage device issues plural slicing voltages to a flash memory. The flash memory issues a soft data to a soft decoder of the controller according to the plural slicing voltages. Firstly, the soft decoder receives the soft data, and performs an error correction process of the soft data according to a predetermined log-likelihood ratio (LLR) parameter set. If the error correction process of the soft data is not successfully completed according to the predetermined LLR parameter set, one LLR parameter set is selected from plural parameter sets of a LLR table and the error correction process of the soft data is performed according to the selected LLR parameter set.

  • Patent number: 8958243
    Abstract: A group classification method includes the following steps. Firstly, a voltage shift parameter table is established. The voltage shift parameter table includes a first positional parameter table corresponding to a first neighboring cell. Then, MN ICI patterns are determined according to N neighboring cells having a significant ICI effect. If the central cell has a first storing state, MN central cell threshold voltage shifts corresponding to the MN ICI patterns are determined according to the voltage shift parameter table, and the first storing state is divided into plural sub-regions. Afterwards, the central cells corresponding to a first number of ICI patterns are classified into a first group of the first storing state. The central cell threshold voltage shifts corresponding to the first number of ICI patterns lie in a first sub-region of the first storing state.
