摘要

本文综述了铁电存储器产品的最新疲劳和老化数据,并讨论了限制非易失性数据保留存储温度的热特性。他们评估了热漂移对多晶薄膜中剩余极化水平的影响。人们发现,升高温度的偏移会导致保留极化的减少。还原是最大温差的函数。电容器极化损耗对可靠集成铁电非易失性存储器件的设计造成制约。

Thermal stability of ferroelectric memories
The authors review the latest fatigue and aging data on ferroelectric memory products and discuss thermal characteristics which limit the nonvolatile data retention storage temperature. They evaluate the effects of thermal excursions on the remanent polarization level in polycrystalline films. An excursion to an elevated temperature has been found to cause a reduction in retained polarization. The reduction is a function of the maximum temperature difference. The loss in capacitor polarization imposes constraints on the design of reliable integrated ferroelectric nonvolatile memory devices.<>
