Effects of Se contents in Ge-Se-Te ternary systems are investigated using edge contact type phase change random access memory cell structures. Increasing the Se content from 6 to 35 at% crystallization temperature and Ovonic switching threshold voltage are increased due to the large grain growth of hexagonal microstructure in the Ge-Se-Te alloys.
