Method of EEPROM

EEPROM is an acronym for electrically erasable programmable memory (EPROM). It is a permanent CMOS chip which is used to store information in computers and other electronic devices. It can be programmed using individual bytes, which are accessible via an address. Each byte is either 1 (or an 0). When the byte is written on the chip it becomes active, and when it is read, the bits are decoded to give instructions.

When writing to an EPROM, the drain and source terminals are grounded. A high voltage from the control gate tunnels into the silicon oxide and is able to reach the floating gate. This allows electrons to flow to the gate and get trapped. This causes the gate to change its contents from 0 to 1. If the voltage is removed from the gate, it becomes uncharged and the EEPROM contents are erased.

EEPROMs are commonly used to store calibration coefficients for sensors, bootloader configurations, and also the status of remote keyless system components. They can also be used to keep status between power changes. This is crucial for ICs powered by batteries as a sudden loss of power can cause the chip to reset.

There are several methods to reprogram an EEPROM however, the majority of them require that the car be in a particular state at the time. For instance, it might be necessary to disconnect the ECU from the battery or to remove the EEPROM and solder it to an test board. Then, the contents of the EEPROM can be read using an EEPROM reader and copied to a different chip.
