Bit widths in MegaWizard RAM 1Port vs 2Port

In Quartus v7.0, why is there a difference in the bit widths shown in the Ram 1 Port vs the Ram 2 Port?

RAM 1 Port contains all bit widths from 1 thru 256

but RAM 2 Port skips around? 1-9, 16, 18, 32, 36, etc

I would think they would be the same.

    Hello,

    Which did you choose "How do you specify the memory size" in the 1st page? The bit widths which you can specify depends on that.

    Thanks,

    You can just type in the bit width you want in the box - you don't have to choose from the choices in the drop-down list.

    Changing the memory size from words to bits added just a few more numbers in the "How wide ..." drop-down list, but it wasn't exhaustive.

    I am going with just typing it in.
