HOW ENABLE RAM2 LPC1768 IN KEIL

That is just one way of doing it. In this case, you have a pointer stored at the memory region the linker decides (probably the first) and pointing to something at a location you have decided.

The linker will automagically use both memory regions if the first can't fit all variables.

And you can specify in the scatter file that a specific source file should have the variables in a specific memory region.

Or you can specify that a variable should be at an absolute address (as long as you don't also try to give it an initial value).

Or you can specify that a range of variables in a source file should be placed in a specific memory region.

So a huge number of options available.
