I have to solve the following problem ...
I need to address a 1Gbit memory (with 26 address lines), but the device in charge to do this operation has only 24 address lines. I read somewhere that usually in these cases the problem is solved by using a portion of the data bus in order to decode the address lines "missing", but I have no idea how this thing could be implemented.
Someone could give me an explanation or what I should looking for?

Just to be clear, between memory and device, I have another device fully connected to the Prom (26 lines), so I think I need a kind of protocol inside this device, in order to decode from 24 to 26 lines.
