Check out Microchip's I2C EEPROMs at www.microchip.com

Their datasheets are very descriptive on I2C usage and their chips are
capable of storing 2000 bytes.

If you need INSTANT write capability (note that I2C chips typically require
anywhere from 1ms (fast write) to 10ms (normal mode) to store each byte or
page of bytes (16 bytes)), then check out www.ramtron.com for their
ferroelectric RAM chips.  These can be written instantaneously and virtually
for an unlimited number of read/write cycles (I think).
