内存的原理和时序(SDRAM、DDR、DDR-Ⅱ、Rambus_DRAM)-The principle and the timing of the memory (SDRAM, DDR, DDR-II, Rambus_DRAM)

SDRAM 接口程序，里面涵盖 datasheet，原理容易懂，对学习ddr有兴趣的可以下来看看。-SDRAM interface program, which covers the datasheet, easy to understand the principle of learning ddr can look down.

嵌入式DDR时序方面的书籍，对调试时序有帮助(The principle and timing.Rar of DDR)
