Analysis of failure time in phase change memory
摘要
Abstract
An acceleration test was carried out to have a deeper understanding on retention characterization of failure time in phase change memory. As the time flows, the resistance would decrease under a high temperature, which can also be induced from the Arrhenius model. The higher the temperature, the shorter the failure time. The distributions for different values of initial RESET resistance suggested that improving the active volume of chalcogenide amorphous region will be beneficial for the retention reliability. The failure time distribution of different cells also represent a hypothesis that the grain growth with nucleation existing in the amorphous region induces a shorter time, while the grain growth at the boundary between amorphous/crystalline regions induces a longer one.关键词
