Phase-changeable memory devices including an adiabatic layer |
摘要 |
Phase-changeable memory devices include a lower electrode electrically connected to an impurity region of a transistor in a substrate and a programming layer pattern including a first phase-changeable material on the lower electrode. An adiabatic layer pattern including a material having a lower thermal conductivity than the first phase-changeable material is on the programming layer pattern and an upper electrode is on the adiabatic layer pattern.
