Hello All,

Can any explain me why differential clocks are required in DDR memories?

Is that for transferring 2 or more words in a single clock? Its not convincing me.

I addition to it, Burst length is about the amount of data transfered.

Lets say i have a burst length of 4 for 4 byte data so a total of 16 bytes transferred.

What is gonna be difference in selecting a burst ordering of 0,1,2,3 or 1,2,3,0 or 2,3,0,1...

Thanks and Regards,
Selvam Anand:)
