Actually a question.....

This is not actually an issue, but a question.
If we use Arduino Mega for this project, do we still need the 2 shift registers?
As I understand, Arduino Mega has enough pins to directly control all the lines of the EEPROM.

Thanks,

You don't need the shift registers with Arduino Mega. Mega has 54 digital IO ports:D
