与Ge_2Sb_2Te_5相比,Al_(1.3)Sb_3Te具有更高的晶化温度(约210 ℃)、更大的晶化激活能(3.32 eV)和更好的数据保持能力(124 ℃ 10年),是一种很有前途的相变存储材料。此外,Al 1.3Sb3Te显示出快速的相变速度,并结晶成均匀嵌入的晶体结构。该电压脉冲宽度仅为10 ns,可实现Al 1.3Sb3Te基相变存储单元的可逆操作。此外,基于Al 1.3Sb3Te材料的相变存储器单元还具有良好的耐久性(类似于2.5 × 10(4)次循环)和类似于10(2)的足够的电阻比。(C)2011年美国物理学会。[doi:10.1063/1.3616146]
Comparing with Ge2Sb2Te5, Al1.3Sb3Te is proved to be a promising candidate for phase-change memory use because of its higher crystallization temperature (similar to 210 degrees C), larger crystallization activation energy (3.32 eV), and better data retention ability (124 degrees C for 10 yr). Furthermore, Al1.3Sb3Te shows fast phase change speed and crystallizes into a uniformly embedded crystal structure. As short as 10 ns width, voltage pulse can realize reversible operations for Al1.3Sb3Te based phase-change memory cell. Moreover, phase-change memory cell based on Al1.3Sb3Te material also has good endurance (similar to 2.5 x 10(4) cycles) and an enough resistance ratio of similar to 10(2).
