For a really large memory, how about extending an idea that's been
mentioned in this list before : driving DRAM from a PIC. One possibility
might be to wrap a PIC around a self-refresh DRAM - these have a pretty
low current consumption in self-refresh mode, and the PIC could be used
to provide the self-refresh pulses and a convenient interface.

NEC offer a 'silicon file memory' that's even lower power (though perhaps
not lower power per bit than 16Mbit self-refresh) but it dosen't seem to
be easily available above 1Mbit.
