摘要: A method of programming a phase change memory device is disclosed. Write data is programmed in a plurality of phase change memory cells by applying write pulses to each of the plurality of phase change memory cells. Whether each of the phase change memory cells is programmed is verified by applying at least one verification pulse to each of the phase-change memory cells. A number of applications for the at least one verification pulse and the intervals between respective applications of the at least one verification pulse are varied in accordance with a verification result for each of the phase-change memory cells.

摘要: A method of processing data in a resistive memory device comprises performing a write operation to store data into a resistive memory of the resistive memory device and to store program information of the data into a cache memory. The method further comprises performing a first read operation to read the program information from the cache memory during a program-to-active time, and a second read operation to read the data from the resistive memory after the program-to-active time if the program information is not read from the cache memory during the program-to-active time.
