US 2019/0095278 A1 · DECODING METHOD AND DEVICE UTILIZING FLASH CHANNEL CHARACTERISTIC AND DATA STORAGE SYSTEM

Abstract

A decoding method and device utilizing a flash channel characteristic and data storage system, wherein the method comprises: acquiring a probability density function curve diagram; determining a to-be-corrected data position according to the current situation of the probability density function curve diagram; transmitting the to-be-corrected data position to a low-density parity check module to perform an operation to correct the to-be-corrected value. The embodiment of the present invention considers the current situation of the probability density curve diagram when determining the to-be-corrected data position, namely, selects different solutions to determine the to-be-corrected data position on the basis of the current situation of the probability density function curve diagram, thus reducing the data transmitted to the low-density parity check module to perform an operation, and reducing operation workload and power consumption.
