Method of EEPROM

EEPROM is an acronym for electrically erasable memory that is programmable (EPROM). It is a non-volatile CMOS chip that is used to store data in computers and other electronic devices. It is programmed to store individual bytes that can be accessed using an address. Each byte is either a 1 (or an 0). When a byte has been recorded to the chip it becomes active. The bits are encoded into instructions when the byte is read.

When writing to an EPROM the drain and source are grounded. A high voltage channeled from the control gate travels through the silicon oxide and into the floating gate, causing electrons to flow into it and get trapped. This causes the gate's content to change from a 0 one. When the voltage is cut off the gate ceases to be charged, and the contents of the EEPROM are erased.

EEPROMs can be used to store calibration coefficients of sensors, bootloader configurations, and the status of remote keyless system components. They can also be used to maintain state between power changes. This is especially crucial for ICs that are powered by batteries, since a sudden power loss could 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 certain condition at the time of. It might be necessary, for example, to disconnect the battery and ECU or to remove the chip and place it on a test board.
