想象一下，你正处于打印论文的最后阶段。那是1980年，一个炎热、朦胧的夏日午后。地平线上酝酿着一场雷雨。紧张和疲惫，你忘了把文件保存在硬盘上。突然，一道闪电劈下！你的电脑关机了。你的最后一章丢失了。不幸的是，你渴望有一天，你写的所有东西都能在你写的时候自动存储在一个非易失性存储系统中，即使停电也不会消失。我需要什么才能让这一切发生？你扪心自问答案是一种快速、随机存取的固态存储器，它便宜、可靠，最重要的是，它本质上是非易失性的，也就是说，它的行为像磁盘存储系统。当你在考虑电子未来的时候，想象一下你有一张电子智能卡，你可以用它来做任何事情，从为紧急救援人员提供你的健康记录到处理你的所有费用，而不必签署信用卡收据或支票。现在，让你的思绪快进到1998年，进入非易失性铁电随机存取存储器的新世界，继续往下读吧！
Imagine you are in the last stages of typing your thesis. The year is 1980, and it's a hot, hazy summer afternoon. A thunderstorm brews on the horizon. Tense and tired, you have forgotten to save the document on your hard disk. Suddenly, lightning strikes! Your computer shuts down. Your final chapter is lost.Wistfully, you long for the day when everything you write is automatically stored in a nonvolatile memory system as soon as you write it and does not vanish if there's a power cut. What do I need to make this happen? you ask yourself. The answer is a fast, random-access, solid-state memory that is cheap, reliable and, most important of all, intrinsically nonvolatile—that is, it behaves like a magnetic disk storage system. And while you're contemplating the electronic future, imagine also that you have an electronic smart card that you can use for everything from providing emergency crews with your health records to transacting all your expenses without having to sign a credit card slip or a check. Now, fast-forward your mind to 1998, enter the new world of nonvolatile ferroelectric random-access memories—and read on!
