active and when it is read the bits are decoded as instructions When writing data into an EPROM the source and drain are grounded A high voltage channeled through the control gate travels through the silicon oxide to the floating gate causing electrons to flow through it and become trapped The gates contents to change from a 0 to a 1 If the voltage is removed from the gate it becomes uncharged and
