EEPROM Method

The EEPROM is an electrically eraseable read-only memory programmable car keys (EPROM). It is a non-volatile CMOS memory chip that is utilized in computers and some other electronic devices to store information. It can be programmed with individual bytes, which can be accessible via an address. Each byte may be one or zero. When the byte is written on the chip, it becomes active and, when it is read the bits are decoded as instructions.

When writing into an EPROM, both the source and drain are grounded. A high voltage from the control gate tunnels into the silicon oxide and reaches the floating gate. This allows electrons to flow to it and become trapped. This causes the gate to change its contents from a 0 into a 1. When the voltage is cut off, the gate becomes uncharged, and the contents of the EEPROM are erased.

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

There are a few methods to reprogram an EEPROM however, the majority of them require that the vehicle be in a specific state at the time. It might be necessary, for example, to disconnect the battery and ECU or remove the chip and place it on a test board.
