Incidentally, I too wanted to get a detailed understanding of DDR2. I
read Upgrading and Repairing PCs (17e), plus a number of other sources.
I came away from those sources feeling my understanding was less than I
hoped for. What addressed my needs, and what I highly recommend, is a
paper called "What Every Programmer Should Know About Memory" by Ulrich
Drepper from RedHat. The early part of the paper gives an outstanding
description of DRAM. The paper initially ran as a series in "Linux
Weekly News". It is now available as a 114 page PDF at
http://people.redhat.com/drepper/cpumemory.pdf 

The theme of the paper is performance optimization, but the DRAM
description at the early part of the paper is worthy in itself.
