This should probably be moved to cisco-nsp if it gets any more in-depth,
however:

Although you're probably asking for exactly what you say, config memory, it
might also be useful to use prefix-lists to filter routing announcements:

and the notes on bug CSCdk93005 seem to indicate that prefix-lists do make a
difference and should be used over access-lists for filtering routes...

Hope that helps,
