Usualy, this kind of EEPROMS have tree or four signals to configure an address. There are two signals (I2C bus signals) that are common to all the memories, and are connected to the microcontroller. You have to force a different address to every memory in order to share the same bus.
The access to the memory via the I2C bus need an address wich value must be selected by your program.

Multiple memories...

Hello,

Don't forget you can use a 2 to 4 or 3 to 8 encoder to access more
chips if you have limited i/o pins.

Bye.
