EEPROM is the abbreviation for electrically eraseable memory that is programmable (EPROM). It is a permanent CMOS memory chip used in computers and some other electronic devices to store information. It can be programmed to store individual bytes that can be accessed using an address. Each byte can be either a 1 (or an 0). When the byte is written to the chip, it becomes active, and when it is read, the bits are decoded as instructions.

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

EEPROMs are typically used to store calibration coefficients for sensors, bootloader configurations, and the status of remote keyless system components. They can also be used to keep status between power changes. This is especially important 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 car keys an EEPROM, but most of them require that the vehicle be in a certain state at the time. For instance, it might be necessary to disconnect the ECU from the battery, or remove the EEPROM and connect it to an test board.
