I've seen schematics to interface common 72pin simm memory to
microcontrollers, which should be fast enough.  I can't tell you off
hand where, but there should be some resources online...

http://www.google.com/search?q=cache:Mvs1fvDDlfU:fstewart.ne.mediaone.net/DaEtiCpesItgaeicisDigitalMemoryNews.shtml+pic+microcontroller+72+pin+memory+interface&hl=en

has some info (It is a cached web page, the original is missing - copy
and paste it into your browser, removing spaces and making sure it's all
on one line)

The best source of information on memory, though, is going to be the
manufacturer.  Try motorola, intel, amd, atmel, etc.
