Working Principles

The AT27BV4096-12JU is based on Flash memory technology. It utilizes floating-gate transistors to store charge, representing binary data as 0s and 1s. When data needs to be stored, the appropriate voltage is applied to the control pins, allowing electrons to tunnel onto or off the floating gate. This alters the threshold voltage of the transistor, enabling the storage of data. The stored data can be read by applying appropriate voltages and sensing the resulting current flow.
