While I was reading about memory architecture from the CMSC 22200's Lecture 17 of University of Chicago, I got stuck on determining the meaning of the word "CS" used for describing a bus as part of memory channel:
However I didn't find any additional source pointing out that bus. And furthermore, I found on different reference that:
The memory channel is made up of a data bus and an address/comm and bus.
So, I don't know from where they got the information about the "CS bus"? And what is it exactly?
