Abstract
A data compensating method for a flash memory is provided. Firstly, a first threshold voltage distribution curve of the cells of the flash memory with a first storing state is acquired. Then, a second threshold voltage distribution curve of the cells of the flash memory with a second storing state is acquired. Then, a first occurrence probability of a first type ICI pattern of the first storing state is calculated according to a statistic voltage range and the first threshold voltage distribution curve. A second occurrence probability of the first type ICI pattern of the second storing state is acquired according to the statistic voltage range and the second threshold voltage distribution curve. During a read cycle, storing states of central cells corresponding to the first type ICI pattern are compensated according to the first occurrence probability and the second occurrence probability.
