No, different address space.  The 7 or 10 bit address refers to the
addresses of slave modules on the IIC bus.  This has nothing at all to do
with the EEPROM's internal address space.  By the way, almost everyone uses
7 bit addressing.  127 possible slaves is usually WAAAAAYYYY more than
enough.  Also, most EEPROM chips only use 7 bit addressing, and often have
most of those hard wired.  Usually you only get to chose the low 1 or 2
address bits the chip will respond to.  Yes, that means you can't put more
than 2 or 4 of these chips on the same IIC bus without some external
selection scheme.
