Working Principles

The AT24C64W-10SC-1.8 utilizes electrically isolated floating-gate transistors to store data. When programming or erasing data, a high voltage is applied to the gate, modifying the charge on the floating gate. This charge alteration determines the stored data state (0 or 1). During read operations, the stored charge is sensed, allowing retrieval of the stored data.
