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, MICI patterns are determined according to N neighboring cells having a significant ICI effect. If the central cell has a first storing state, Mcentral cell threshold voltage shifts corresponding to the MICI 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.
