What is an EEPROM?
Electrically Erasable Programmable ROM or EEPROm is a rewritable memory chip that holds its content without power. The two main categories of EEPROM interfaces are Serial bus and Parallel bus. These interfaces require between 1 and 4 control signals for operation, resulting in a memory device in an 8-pin (or less) package. Most common EEPPROM serial interface types are SPI, I²C, Microwire, UNI/O, and 1-Wire.  (Souce: EE Times, Wikipedia http://en.wikipedia.org/wiki/EEPROM)
