Abstract
Official abstract text for this publication.
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, M N ICI patterns are determined according to N neighboring cells having a significant ICI effect. If the central cell has a first storing state, M N central cell threshold voltage shifts corresponding to the M N 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.
First claim
Opening claim text (preview).
What is claimed is: 1. A group classification method for a solid state storage device, the solid state storage device comprising a central cell and plural neighboring cells around the central cell, each of the central cell and the plural neighboring cells being programmable into one of M storing states, N neighboring cells of the plural neighboring cells having a significant ICI effect, the group classification method comprising steps of: establishing a voltage shift parameter tab…
