Shawn, other's have mentioned FIFOs but they are very expensive and very
limited in size if you want to store 1-2MB. Industry-standard 512K x 8 SRAM
costs around $20 (~70ns) in single quantity.

   The nice thing about FIFOs is that they are very easy to interface to with
little or no `glue' logic. I looked at FIFOs from several vendors when I was
researching my logic analyzer. IDT seems to be a clear winner as far as price
and capacity. You mentioned "money was no object". In that case they have
devices up to 128K. Again, they are `extremely' expensive...

   If you go with 512K x 8 SRAMs, you will need to generate a 20-21 Bit
address and provide 2-4 chip-selects. You can easily do this in a simple CPLD
or 74x family `glue' logic.
