Method of EEPROM
EEPROM is the abbreviation for electrically eraseable programmed memory (EPROM). It is a permanent CMOS chip which is used to store data in computers and other electronic devices. It is programmed to store individual bytes that are accessed with an address. Each byte is either a 1 (or a 0). If a byte has been written to the chip it becomes active. The bits are then converted into instructions when the byte is read.
When writing to an EPROM, the drain and source terminals are grounded. A high voltage channeled through the control gate passes through the silicon oxide to the floating gate, causing electrons to flow into it and become trapped. This causes the gate to change its contents from 0 to 1. When the voltage is removed, the gate becomes uncharged, and the contents of the EEPROM are erased.
EEPROMs are commonly used to store calibration coefficients for sensors, bootloader configurations, and the status of remote keyless system components. They can be utilized to maintain the state of the system between power-related transitions. This is especially crucial for ICs that are powered by batteries since a sudden power loss could cause the chip to reset.
There are a few ways to reprogram an EEPROM. However, most of them require the car to be in a specific state. It might be necessary, for instance to disconnect the battery and ECU or remove the chip and place it on a test board. The contents of the EEPROM chip can then be read using an EEPROM Reader and copied onto another chip.
