Abstract

The invention provides a target data decoding method and device, electronic equipment and a storage device, and belongs to the technical field of data decoding. The method comprises the steps that target data are read from a storage medium, and the storage medium comprises a plurality of storage units; under the condition that decoding of the target data by adopting a preset decoding mode fails, a target storage unit is determined according to position information pre-stored in a memory, and the position information comprises the specific position of a specific storage unit; the initial credibility of the target storage unit is changed into target credibility, wherein the credibility value of the target credibility is lower than the credibility value of the initial credibility; and the target data of which the credibility is changed is decoded by adopting a soft decoding mode. According to the invention, the target data decoding success efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of data decoding, and in particular to a decoding method, device, electronic equipment and storage device of target data. Background technique [0002] The structure of the NAND FLASH storage cell package includes control gate (CG), floating gate (FG) and oxide layer (Oxide) from top to bottom. , electrons adsorbed on the floating gate can perform the action of reading or writing (Program), forming Logic0, when a high voltage is applied to the lower end, electrons leave the floating gate to complete the action of erasing (Erase), forming Logic1. NAND FLASH must Erase first and then Only after Program, after Erase is logic1, after Program is logic0, when writing or reading or Erase, the electrons will continue to move so that the oxide layer below will gradually become thinner and even be punctured, which will cause lack of isolation As a result, the cell may be broken, and the original logic1 will...
