Working Principles

The 25LC160AT-E/ST utilizes a floating-gate transistor structure to store data. When data needs to be written, an electrical charge is applied to the floating gate, trapping electrons and altering the transistor's behavior. This change in behavior represents the stored data. Reading the data involves sensing the transistor's behavior and decoding it back into binary information.
