    What Language are you writing the code with? A generic 8051 only supports 64K of RAM. So you will have to use another port pin to address 128K. The code will then have to insure the correct memory is selected. In this case a 3 to 8 decode will work. What is the part number of the chip you are using? Does it support 128K directly?
