Working Principles

The AT45D161-TI utilizes flash memory technology, which stores data by trapping electrons in floating gate transistors. When data is written, a high voltage is applied to the control gate, allowing electrons to tunnel into the floating gate. This process alters the transistor's threshold voltage, representing a binary state (0 or 1). During read operations, the stored charge is measured to determine the stored data.
