A question about the block memory

I used 82% of the total block memory bits. However, Quartus cannot place all RAM cells in design. The FPGA device which I am using is EP3SL150. Please tell me, what is the problem? How to successfull...

For M9Ks you will need more rams that is available. You would need 16 M9Ks (at 8 bits ) x 32 rams per memory. That is 512 M9Ks, just for one 32kx128 bit ram.

Basically, you need more ram that is available. Why do you need so much ram? why cant you ujse external ram?
