In this paper, the two time instability factors in phase change memory, amorphous resistance drift and spontaneous crystallization process, are studied based on Ti2.75(SbxTe)97.25 and Ti6.85(SbxTe)93.15. The drift coefficients of both components are calculated and compared under room temperature. The reason why the drift coefficient decreases with the Ti concentration increases is discussed based on the band structure model of amorphous phase change materials. And the data retention change trend is also presented. The experiment results and the physical explaination can also be extended to other metallic element doped SbxTe alloy phase change materials.
