"Does an EEPROM work the same way as an EPROM? ie can I use it on a bus and just r/w memory addresses from it? "

If you are using it only for code memory then you need to use PSEN and !RD.

If you are using it for data memory (that also is modified ) when the program runs you need to use the !RD and !WR.

Or if its only "constant" data like a look-up-table then you can get away with only !RD.

What is your actual use ?
