Hi,
i don't have a circuit to replicate 2x 8-bit memories and I can't back up this answer with proven timings but, the following are tentative answers to your questions:
1) See attached diagram. I have not been able to confirm these connections are correct
2) See the diagram and also relate to figure 12 of the datasheet
3) Again, similar to figure 12 except BLE and BHE are always inactive. and the address increments by 1 instead of 2.
regards,
Mike
