    What good is that going to do? Either way the variables are going to be loaded into RAM, regardless where in non-volatile memory they are stored. But of course, if their value changes slowly, you might want to consider storing them AND maintaining the value in non-volatile memory.
    Can you add external RAM/SRAM?
