DRAM speed and timings

[msuffidy]

It seems the clock rate on ram keeps going up. Wold it be safe to say though that fundamentally DRAM has always had a basic access rate of around 60ns? So it seems the cas tmiings etc of the dram keeps going up as well as the clock rates, but for some reason faster DRAM is better?

It's about deep pipelining. You issue one command, then another, yet another one, and some more, and after your 60ns or whatever the first result arrives, and then the others arrive at a faster rate than with older RAM technology of equal latency.

This benefits mainly sequential throughput. Random access, not so much.

Besides, your 60ns seems to refer to full row access (RAS)? Reading from the current row (CAS) tends to be no more than 10ns. Again, a difference mainly meaningful for sequential access.
