Your max depth is 512, making a 512x9 RAM, which I thought would actually use 6. At 640x24, I'm not quite sure how it would be done with 4 M4Ks. Your width and deptch aren't nice powers of 2, and you end up wasting bits in both directions. If you can't reduce the depth a little, maybe you have open registers in the design that could be used to build out the last M4K?
