How did you use the array? did you follow the coding guidelines to infer a ram? if you did not, then synthesis will take a very very long time for such a large array.

640x480 is a very very large array to have inside an FPGA, and would use a significant portion of the internal ram (or all of it, depending on the device). So post your code, and give us more details about the device you are using.
