  Usually the reason why people use EEPROM is because they want their
data to be non-volatile.  The drawback of normal EEPROMS are that
they require quite a long write cycle.

I would seriously consider looking at FRAM as well, if I were you.
It very reliable, software compatible with serial EEPROM but just
much much faster, because there is no writing cycle as in the case
with EEPROM.   This type of devices are the ideal replacement for normal DRAM
or SRAM, especially if you want it to be non-volatile.
