This library is based on several projects:
The Arduino EEPROM library found here:
http://arduino.cc/en/Reference/EEPROM
The 24C256 library found here:
http://www.arduino.cc/playground/Code/I2CEEPROM
The 24C512 library found here:
http://www.arduino.cc/playground/Code/I2CEEPROM24LC512
Our project page is here:
http://www.arduino.cc/playground/Code/I2CEEPROM24C1024
From the datasheet:
The AT24C1024B provides 1,048,576 bits of serial electrically
erasable and programmable read only memory (EEPROM) organized
as 131,072 words of 8 bits each. The device<EFBFBD>s cascadable
feature allows up to four devices to share a common two-wire
bus.
