This is a good straighforward translation of the standard:

And, Intel's version is a pretty easy read as well:

The JEDEC version is the official one, but I hate trampling through
multiple pdfs to try and find one little bit of information, these are
much more concise. Both explain byte 31, and much of the standard is the
same between sdram/ddr/ddr2.
