Zusammenfassung:A data storage device, a memory system and a computer system are provided to improve the lifespan and writing performance of the data storage device using at least two or more heterogeneous non-volatile memories by distributively store user data and meta data. A non-volatile memory system(1000) comprises a data storage device(100) and a controller(200). The controller is constructed so as to communicate with the outside through one of various interface protocols, and controls the data storage device. The data storage device comprises a memory cell array(130) consisting of flash memory cells. The memory cell array is divided into the first data storage region(110) and the second data storage region(120). The first and second data storage region consist of heterogeneous non-volatile memory cells having different properties.
