I haven't really understood your requirement, but if you are looking for some heap storage stuff, then avr-libc might be your place. The malloc routines there allocate the memory using heap variables. Coming back to the requirement, instead of using external ram via serial interface, you want that to be integrated with SRAM seamlessly...Have I got it right?
