EEPROM Method

EEPROM is the abbreviation for electrically eraseable programmed memory (EPROM). It is a permanent CMOS chip that is used to store information in computers and other electronic devices. It is programmed to store individual bits of data that can be accessed using an address. Each byte could be a 1 or a 0. When the byte is written on the chip, it is activated and when it is read, the bits are decoded to give instructions.

When writing to an EPROM the drain and source are grounded. A high voltage from the control gate is absorbed into the silicon oxide and gets to 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 is uncharged and the EEPROM contents are erased.

EEPROMs are commonly used to store calibration coefficients for sensors, bootloader configurations and the status of remote keyless system components. They can also be used to maintain the state of the system between power transitions. This is particularly important for ICs that are powered by battery, since a sudden power loss will cause the chip to reset.

There are a variety of ways to reprogram an EEPROM however, the majority of them require that the vehicle be in a particular condition at the time of. For instance, it could be necessary to disconnect the ECU from the battery or to take the EEPROM out and solder it to an test board.
