RESISTANCE MEMORY DEVICE AND METHOD OF CONTROLLING INPUT AND OUTPUT OF THE SAME

摘要

PURPOSE: A resistance memory device and a method of controlling input and output of the same are provided to improve the reliability of ECC code trough the margin of reading data by reducing the distribution of resistance distribution of resistive memory cells. CONSTITUTION: The input/output operation of an ECC code is separated from the input/output operation of data(S100). The separation step of the input/output operation is performed based on a mode signal and an address signal. The condition of the input/output operation of the ECC code is stricter than that of the input/output operation of data(S300). The separation step of input/output operation includes an writing operation of an ECC code from data writing.
