A Si2Sb2Te5 (SST) memory array with density of 4 Gbit/in.2 was fabricated by ultraviolet-imprint lithography. The contacted area of SST with electrodes in memory cell was 0.0392 μm2. Crystal structure transformation of SST film was studied. Adhesion strength of sample interface was tested by Nano Indenter®. Electrical property of SST electrical probe storage (EPS) system was measured. Resistance of...
