Re:
Cool, that's interesting.
Followup questions:

So PC2100 means (64 bits * 266Mhz) / 8 = 2128.
But why is it 64 bits?
Where do 64bits and 266Mhz come from?
Why is it called PCxxxx?
Why is it called DDR and why is it called RDRAM?

64 bits is the width of the memory bus for pretty much all systems today, though graphics cards often have 128.
Don't know why they chose "PC" as the prefix.
DDR stands for "Double data rate"
RDRAM stand for "rambus dynamic ram"
http://www.radiativenz.com/guides/memoryguide/ is a good overview that should help with any more questions you might have
