Working Principles

The 25LC160AT-I/SN utilizes a floating-gate transistor structure to store data. When data needs to be written, the IC applies a high voltage to the gate, allowing electrons to tunnel through an insulating layer onto the floating gate. This process traps the charge, representing a logical "1" or "0". Reading the data involves sensing the charge on the floating gate.
