Abstract

The invention discloses a file operation processing method and device. According to the scheme, the reliability of user data and metadata of the user data is guaranteed at the same time by providing a dual mechanism based on CRC error detection and ECC error correction, the ECC error correction is matched with two-stage CRC error detection, so that the error correction capability to a certain degree is provided for a file system; and particularly, ECC error correction and CRC error detection functions are provided for user data and metadata thereof at the same time, the stability of the file system can be improved, and the safety of the user data can be improved, so that the reliability of data storage is improved by introducing a verification and error correction mechanism into the file system, and the problem that equipment based on storage media such as TLC / QLC is insufficient in storage reliability in the industrial embedded field can be effectively solved.

Description

technical field [0001] The present application belongs to the technical field of computer file systems, and in particular relates to a file operation and processing method and device. Background technique [0002] NAND (computer flash memory device) has continuously entered the era of 30nm, 20nm and 10nm from 50nm, which has increased the density of transistors, increased the capacity of NAND, and reduced costs, but the improvement of NAND technology means that the silicon dioxide layer used to block electrons has become more and more The thinner it is, the worse the reliability will be. Therefore, the decline in performance and reliability has become a disadvantage of NAND devices such as TLC / QLC (triple-level storage cell / quad-bit cell) flash memory. [0003] In order to meet the user's demand for cost and capacity, it is necessary to introduce a certain verification and error correction mechanism in the file system, so as to improve the reliability of data storage and be...
