PHASE CHANGE MEMORY DEVICE AND CONTROLLING METHOD THEREOF

摘要

PURPOSE: A phase change memory device and controlling method thereof are provided to improve the program speed and efficiency by omitting programming of code data. CONSTITUTION: The phase change memory chip is fixed to the printed circuit board through the IR (Infrared) reflow process(S10). The reset data is changed due to heat added in the phase-change memory chip to the state of the set data(S20). The operation in which set data is lighted in the memory cell of the phase-change memory chip is deactivated(S30). The code of reset data is programmed at high speed in the phase-change memory chip(S40).
