I don't know how well it has lived up to its promises.  I was
just taken a back by the complexity of Rambus.  If you do follow
the links to the technical information you find hundreds and
hundreds of pages of documentation on how Rambus squeazes the
last bit of juice of the 50 million attached processing
transistors.  I really think that the complexity of the
Rambus interface would simply dwarf the chips we have now.

SDRAM and DSDRAM give us a big step up in performance for a
relatively small increase in complexity and cost.  The
memory interface part of the chip does become a little
larger and more pins are needed but nothing like rambus.
I agree with Eugene on this.
