DATA STORAGE DEVICE AND A DATA STORAGE SYSTEM WITH THE SAME, WHICH DIFFERENTLY APPLY THE SEED OF A RANDOMIZER TO EACH PRESET UNIT

摘要

PURPOSE: A data storage device and a data storage system with the same are provided to increasing randomness by selectively randomizing input data.;CONSTITUTION: A controller(20) decides characteristics of first input data. The controller outputs a first control signal based on the decided input data of the first input data. A randomizer(10) selectively randomizes the first input data in response to the first control signal outputted from the controller. An error correction encoder(50) generates the first input data by encoding second input data to error correction codes. A de-randomizer(30) performs reverse randomization of read data which is read in response to a read command from a host.;COPYRIGHT KIPO 2010
