It could be that you are using your memories inneficiently.

For example - in stratix devices you have M4K blocks. On mode allows them to run with 256 x 16 bit words. If you only need 12 bits per word, thats 25% of the memory wasted that nothing else can now use, unless theres some other word with exactly the same data flow as the 12 bit word. This memory is now dead and is a 25% loss.
