51单片机存储器容量需要扩展，增加硬件和软件负担，运行速度慢。
华中科技大学成功研制出我国具有完全自主知识产权的256b相变存储器功能芯片（2009年）和1Mb相变存储器测试芯片(2010年)，其读写速度会比现在快1000倍，可靠性也将提高1000倍。
思政感悟： 勇于创新，民族自信心和自豪感！
The storage capacity of the 51 microcontroller needs to be expanded, which increases the hardware and software burden and slows down the running speed.
Huazhong University of Science and Technology has successfully developed a 256b phase-change memory functional chip (2009) and a 1Mb phase-change memory test chip (2010) with completely independent intellectual property rights in China. Its read and write speed will be 1000 times faster than now, and its reliability will also be improved by 1000 times.
