It can be programmed with individual bytes, which can be accessed using an address. Each byte could be a 1 or a 0. When the byte is written to the chip, it is activated and, when it is read the bits are decoded as instructions.

When writing to an EPROM the source and drain terminals are grounded. key programming near me that is channeled from the control gate passes through the silicon oxide to the floating gate, causing electrons to flow into it and then become trapped. This causes the gate to change its content 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 also the status of remote keyless system components. They can also be used to maintain state between power changes. This is particularly important for ICs that are powered by batteries since a sudden loss of power can cause the chip to reset.

There are several ways to reprogram an EEPROM, but most of them require that the car be in a particular condition at the time of. It could be necessary, for example, to disconnect the battery and ECU or to take the chip off and then solder it to an test board.
