摘要
铁电存储器在航天领域具有很大的应用潜力,研究其辐射效应对其今后的宇航应用有重要意义.利用重离子加速器对1 Mbit铁电存储器进行了单粒子辐射效应试验,分析了铁电存储器的单粒子效应类型及其机理,进行了静态测试模式和动态测试模式的对比试验研究,得到了该铁电存储器发生单粒子翻转的线性能量传输阈值和单粒子翻转截面,以及发生单粒子闩锁的线性能量传输阈值.该试验结果为铁电存储器的空间应用及加固设计提供了参考.
Ferroelectric random access memory(FRAM)is a promising candidate for future data storage in space missions.Its radiation effects need to be well characterized for practical applications.A heavy-ion accelerator was utilized to study the single event effect(SEE)of a 1 Mbit FRAM.The different types and mechanisms of SEE on FRAM is analyzed.Both the static mode and dynamic mode were used for the test.The linear energy transfer(LET)threshold and the cross section of the single event upset(SEU)were tested,as well as the LET threshold of the single event latchup(SEL).The results provide references for the future space application and hardened design of FRAM.
