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

When writing into an EPROM, both the source and drain are grounded. A high voltage from the control gate is absorbed through the silicon oxide and reaches the floating gate. This allows electrons to flow to it and then become trapped. The gate's contents to change from a 0 to a 1. If the voltage is removed from the gate, it becomes uncharged and the EEPROM contents are erased.

EEPROMs are typically used to store calibration coefficients for sensors, bootloader configurations and also the status of remote keyless system components.
