Abstract

A method for selecting the scrambling and descrambling data transmitted in a storage system containing ECC and scramble engines with a seed table is disclosed and the steps comprises: encoding a data sent from a HOST interface by an ECC encoding engine and transmitting the data to a LFSR scramble engine; scrambling the data by the LFSR scramble engine and transmitting to a storage device; creating a seed value and transmitting the seed value to a seed table by the LFSR scramble engine; receiving the seed value from the seed table and the scrambled data from the storage device by a LFSR descramble engine, and descrambling the scrambled data based on the seed value and transmitting to an ECC decoding engine; and decoding the descrambled data received from the LFSR descramble engine and then acquiring the original data sent from the HOST interface.
