    To store data there are three options:

    memory blocks

    registers (of the fabric)

    wires (for constants)

    see if you can use the last two options.

    logic will not store anywherer near as much as ram. you need to get a larger part or re-design your system

    If you are using the megafunction to instantiate the ROM you have a parameterization option to force the logic to be implemented in LEs. Before doing so I would take a look at your implementation to make sure there are not other optimizations you can do first since if your ROM is big, implemented in LEs it'll be slow.
