Memory system having resistive memory device and operating method thereof

Abstract

A memory system includes a resistive memory device comprising a memory cell array including a plurality of resistive memory cells and a peripheral circuit; and a memory controller suitable for generating data bus inversion (DBI) information which corresponds to write data based on an access history of the resistive memory cell corresponding to an address of the write data, and providing the DBI information, the address and the write data to the peripheral circuit, wherein the peripheral circuit is suitable for selectively inverting the write data based on the DBI information and writing the selectively inverted write data in a memory cell selected according to the address among the resistive memory cells.
