It is used to store a variety of things, including serial numbers and other unique information in virtually everything connected to Ethernet and the chip used in printers, charge cards and even blood glucose monitors. It is also used to keep data sequences that govern the operation of microcontrollers and also to provide a means of recovering from power-on reset conditions. The basic EEPROM chip has two field effect transistors. The floating gate is on one side and the control gate is on the other. When the device is powered, electrons are released from the gate and can be held in either one or zero state dependent on the voltage that is applied. The EEPROM can be read by determining the state of these transistors. When the EEPROM state is “0” and it is “0”, it has no value. If the EEPROM state is “1” is the case, it has a value of 1. Between these two states, no data is saved, however, it can still be written. The EEPROM can also be erased by applying a specific voltage to the gate for a short period of time. The EEPROM has the advantage that it can be erased and written to with no external circuitry. This makes it a great choice in systems where memory is required to be updated regularly for example, remote keyless system microcontrollers. However, there are other memory chip models that provide similar functionality and are better suited for long-term storage and retrieval of large files. Modern flash memory chips, for instance, are very popular and can be found in computers and digital cameras. These are used to store multimedia files for long-term storage and retrieval.

Scan tools have a greater computing capacity than code readers and read more error codes. They also display live data graphs, and save data that can be later analyzed. Some tools are capable of performing more complex functions like changing the programming of an ECU or offering enhancement options for performance. These tools are used by auto technicians who are professionals and are usually more expensive than scanners for simple tasks.
