EEPROM Method

The EEPROM is an electrically eraseable read-only memory programmable (EPROM). It is a permanent CMOS chip which is used to store data in computers as well as other electronic devices. It is programmed using individual bytes, which are accessed using an address. Each byte is either a 1 (or an 0). When a byte has been written to the chip it is activated. The bits are converted into instructions when the byte is read.

When writing to an EPROM the drain and source terminals are grounded. A high voltage from the control gate passes into the silicon oxide before it reaches the floating gate. This allows electrons to flow to the gate and get trapped. This causes the gate to change its contents from a zero to a 1. When the voltage is removed the gate ceases to be charged and the contents of the EEPROM are erased.

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

There are a variety of methods to reprogram an EEPROM, but most 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 remove the EEPROM and solder it to the test board.
