%X This paper investigated phase change Si1Sb2Te3 material for application of chalcogenide random access memory. Current--voltage performance was conducted to determine threshold current of phase change from amorphous phase to polycrystalline phase. The film holds a threshold current about 0.155~mA, which is smaller than the value 0.31~mA of Ge2Sb2Te5 film. Amorphous Si1Sb2Te3 changes to face-centred-cubic structure at \sim 180℃ and changes to hexagonal structure at \sim 270℃. Annealing temperature dependent electric resistivity of Si1Sb2Te3film was studied by four-point probe method. Data retention of the films was characterized as well.
