Hi - I'm trying to simulate an interface for a DDR2 unbuffered DIMM, but I'm having trouble finding the specification for the DIMM (trace lengths, topologies, etc.). On the JEDEC site I'm able to find specs for DDR2 registered DIMMs and SO-DIMMs, but the unbuffered DIMM eludes me. Is there a spec for this, and does anyone know the number or how to obtain it? (I've tried the DIMM vendor, but the answer is, "Go to the JEDEC site..."). Thanks, Bob Perlman Cambrian Design Works ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List FAQ wiki page is located at: http://si-list.org/wiki/wiki.pl?Si-List_FAQ List technical documents are available at: http://www.si-list.org List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
