Abstract

A storage control method, suitable for a storage device, comprising: generating an error correction code (Error Correcting Codes, ECC) control parameter according to a non-volatile control parameter and a volatile control parameter, wherein the non-volatile control parameter is stored In a non-volatile storage area in the storage device, the volatile control parameter is stored in a volatile storage area in the storage device; an ECC function is controlled according to the ECC control parameter, so that access from a memory cell array The data of a storage location is processed or not processed by the ECC function.

Description

Technical field [0001] The present invention relates to a storage control method, a storage device. Background technique [0002] Error Correcting Codes, ECC) is a technology used to correct data errors, which are widely used in communication, data storage and other fields. By adding additional ECC data on the original data, even if the data is subject to external interference or noise during transmission, the receiving end can still be corrected back to the original correct data, thereby reducing the data error rate. [0003] However, the system performs ECC processing takes an additional time to perform data comparison and correction, so that the overall performance of the system is lowered. Therefore, there is a need to propose a new technique to solve the above topics. Inventive content [0004] The present invention provides a storage control method and a storage device that enables an error correction code (Error Correcting CODES, ECC) function of the storage device, so th...
