What every programmer should know about memory, Part 1

Requesting editor for single PS or PDF file that includes all seven segments.

This series is announced by U. Drepper some time ago, see here (mhm, and few day ago I grumbled here at linking to blogs...); it is mentioned there that PDF will be released once this series completed.

As all commenters above, I enjoyed reading first installment. However, I think also there are segments that could be further improved, in order to really have this text as ultimate reference for memory related topics. For example, static RAM diagram could be explained better (remember that this text is directed towards programmers, that may have not much EE related background), as well as DRAM refreshing (it is left somewhat unclear how DRAM cell is returned to its initial value after practically destroying this value during read operation - this is say much more clear at block diagram from corresponding Wikipedia article than from Figure 2.7 from text above), etc. That sort of stuff is usually explained in all of its glory detail in digital logic design books (for example in Katz/Boririello seminal work), but maybe it could be worth trying to digest it for this kind of text too...
