Working Principles

The AT93C56A-10PI-1.8 chip utilizes an array of floating-gate transistors to store data. When data needs to be written, a high voltage is applied to the gate of the selected transistor, causing electrons to tunnel onto the floating gate. This alters the threshold voltage of the transistor, representing the programmed data. Reading the data involves sensing the threshold voltage of each transistor in the array.
