Original Abstract Submitted
in order to guarantee data validity of data read from a memory device of the data storage device to a host device, a controller of the data storage device may calculate a cyclic redundancy code (crc) signature of the decoded data and compare the crc signature of the decoded data with a crc signature of the data. the crc signature of the data is generated during a write operation of the data to the memory device. rather than returning an uncorrectable error correction code error (uecc) error to the host device when the crc signature of the decoded data does not match the crc signature of the data, the controller executes the read command again. by using a different buffer to store the decoded data, the controller may confirm whether the error stemmed from the read path or the error was not from the read path.
