yes I know that this is repeat question. I have search EE but I am not satisfied with other answers. I know so much so far
DDR = Dual/Double Data Rate
SDRAM = Synchronous Dynamic RAM (in sync with CPU clock)
I know DDR SDRAM exists because it is in my machine right now. is there a "DDR DDRAM"? I believe there should exist one. what does the first 'D' stand for in DDRAM? I know it is not Dual Data Rate again because last four letters are for Dynamic Random Access Memory.
how do you calculate throughput by looking at the chip's number (PC100, PC133, PC3200, etc.)?
