Abstract
A scramble random seed prediction method with the storage device built-in data copy back procedure is disclosed. The method may predict a scramble random seed before first time programming. The data may be programmed with the scramble random seed based on the pager number of the block B, not block A, before programming data to block A. After data is moved from block A to block B with the storage device built-in data copy back procedure, the data in block B may be have the best scramble random seed. Therefore, compared to the conventional method of scrambling data or data movement, the moved data of this invention may be much more stable with the storage device data copy back procedure.
