how many is a lot? THe megafunction is limited to 16 bit addressing. If you have to use the megawizard/mf, then you will have to generate multiple rams (why not have 3x 1x64k ram in parrallel, 1 bit per ram ?)
Have you worked out exactly how many internal memory blocks your 3 bit word will need? Have you tried inferring the ram in HDL? - Altera_Forum

I could probably try inferring the ram, would that be the best way? - Altera_Forum

Did you try to type in 80000 in the MegaFunction's number of words field?
