I have a meory with size 8704*32. Iw ant to implement it on Cyclone 3 device. Megawizard shows that I need 31 M9K+ some LUts for this memory. Fitter fails and asks for 34 M9K. Any idea?

I think the '12 instances of block RAM were inferred' means that the fitter decided to use memory blocks for some other latches.

Since M9K are dual ported, one M9K can be used for two RAM blocks.

The fitter can also replicate RAM in order to meet timing requirements.
