i dont think the address lines depend on the data lines it is irrespective of the data line it is solely dependant on the memory size...i think for 2k size memory irrespective od the data line it takes 11lines to access the location .....
can u pls explain how ur logic what u have posted ............
i think its not correct that if data line is 16 bit wide it requre only 10 address line.
the 11 address line only indicating that we can access 2^11 locations and the data may be 8 bit or 16 whatever way arranged in that chip plz correct me if i am wrong
