Abstract
The invention provides a data storage device. In one embodiment, the data storage device comprises a memory and a controller. The memory is for data storage. When the data storage device receives first source data to be written to the memory from a host, the controller generates at least one first input data according to the first source data, scrambles the first input data according to a plurality of pseudo random sequences to obtain a plurality of first scrambled signals, calculates a plurality of transmission powers of the first scrambled signals, and selects a target scrambled signal with a lowest transmission power to be stored in the memory from the first scrambled signals.
