According to the doc and schematic above, _RFSH is as your overgeared brain-cell suggested :-) to be connected to PHI2 and one more cap for delaying the _OE/_CE lines should be added. I did so and it still doesn't work. I even connected CS to PHI2 as in the schematic, although I don't think it to make a difference. And it didn't. Eh.. Will have to wait for more time..
