It was DRAM in SIMM packaging, that let you have a fast memory bus off the cpu chip set.
You should spend some time looking at old machine architectures, because what you
say is very 21st century centric. An excellent intro is "Design of a computer - the
Control Data 6600" by J. E. Thornton. Available on Bitsavers
https://bitsavers.org/pdf/cdc/cyber/books/DesignOfAComputer_CDC6600.pdf or you can get the
hardcover printed book.
I need to read that.
I like IBM's book, on the 7030,
and Bell's Books,on the PDP computers.
Three totaly different views, on computing.
I'm not sure which Bell book you mean, but there's Bell and Newell which is a
broad survey of computer architectures. One of the few square books I have ever seen.
