Abstract
A system, a method and a non-transitory computer readable medium for generating soft information. The method may include performing a first set of read attempts of flash memory cells using a first set of read thresholds to provide first read results; calculating for each flash memory cell in response to the first read results, first cell information indicative of a first change-inducing read threshold; performing a second set of read attempts of the flash memory cells using a second set of read thresholds to provide second read results, calculating for each flash memory cell in response to the second read results, second cell information indicative of a second change-inducing read threshold; and generating, for each flash memory cell soft information in response to the first cell information and the second cell information of the flash memory cell.
