有没有人弄过PCM，不知道这东西现在用的多不多
Micron的相关联接如下 http://www.micron.com/products/multichip-packages/pcm-based-mcpPCM(phase change memory：
1.non volatile
2.byte-alterability
3.one million write cycle

补充一段：
PCM offers fast random access times like NOR Flash and RAM technology and also has the ability to write fast like NAND Flash. In addition, PCM is similar to RAM and EEPROM in that it supports
bit-alterable WRITEs (overwrite).
Unlike Flash, no separate erase step is required to change information from 0 to 1 and 1 to 0. And different fromRAM, PCM technology is nonvolatile. However, data retention compares with NOR Flash devices. Currently, PCM technology has WRITE cycle endur-ance that is better than that of NAND or NOR Flash, but less than that of RAM 感觉像铁电,挺贵的吧
