As the other have said, an excellent read if you want to understand how the metal works now. These paragraphs below me away: > if you program the CAS Write Latency to 9, once the ASIC/uP launches the Column Address, it will need to launch the different data bits at different times so that they all arrive at the DRAMs at a CWL of 9. and: > there could be changes in Voltage and Temperature during its course of operation. To keep the signal integrity and data access reliable, some of the parameters that were trained during initialization and read/write training have to be re-run. So now the chips have to dynamically tune the circuity behind each pin to suite the length of each trace it is connected to, and it's temperature. Keep those fingers well away from the board during operation. In fact I imagine a cockroach strolling across the motherboard looking for a comfortable spot at the right temperature could well wreck havoc.
