The bits are then decoded into instructions when the byte is read.

When writing to an EPROM, the drain and source terminals are grounded. A high voltage from the control gate is absorbed through the silicon oxide and reaches the floating gate. This causes electrons to flow in to it and then become trapped. The gate's contents to change from a 0 one. When the voltage is removed from the gate, it becomes uncharged and the EEPROM contents 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 utilized to maintain the state of the system between power-related transitions.
