Now you're talking!!!  Lots of pins give us multiple ports - now how do we
use them?

To begin with: we need to start moving the parallelism of interleaved memory 
systems *within* the memory chips.  We know how to make expensive multichip
memory systems run fast. Trouble is, chip count is very strongly related
to system cost, and everyone wants cheaper systems.

We need memory chips that can keep several memory transactions going within
the chip - that have fast and powerful logic to snarf the data on writes,
and drive the read data out to the bus really quickly when it surfaces.
The various burst modes (page mode, nibble mode) are great, but it's time
that memory handled independent transactions well too.
