Working Principles

The X40020V14-C is an EEPROM memory device that utilizes electrically erasable and programmable floating gate transistors to store data. It operates based on the principle of trapping and releasing electrons in the floating gate, which alters the threshold voltage of the transistor and represents binary data.

During write operations, a high voltage is applied to the control gate, allowing electrons to tunnel through the thin oxide layer and get trapped in the floating gate. This process sets the transistor's threshold voltage to a specific level, representing either a logical "0" or "1". Reading the stored data involves applying a voltage to the control gate and measuring the resulting current flow through the transistor.
