For eMMC storage devices, CRC check plays an important role in the data transmission process. It can detect errors during data storage and transmission to ensure data integrity and reliability. When data is written to an eMMC device, the CRC check calculates a check value and writes it to a specific register of the eMMC. When data is read, the eMMC device recalculates the check value and compares the result with the previously written check value to ensure that there are no errors in the read data.
By using CRC checks, eMMC devices can better protect data integrity and reduce errors in data transmission. For application scenarios that require high reliability and data integrity, using eMMC CRC check is a good choice.
1 What is CRC?
CRC (Cyclic Redundancy Check) is a verification algorithm used to verify the integrity of data. During data transfer
