You can change the address of a chip using the pins 1 and 2. Base address usually is 0x50. If you connect pin 1 of the second chip to 5V it's address changes to 0x51.

in that case, i can't use EEPROM Database right ?

You can connect up to four of these chips to on single I2C bus.

What's a EEPROM database in this context?
