Working Principles

The AT49LV040-70TC operates based on the principles of flash memory technology. It utilizes floating-gate transistors to store and retrieve data. When data is written, charges are trapped in the floating gate, altering the transistor's behavior. These charges can be erased by applying a high voltage, allowing the transistor to return to its original state. This mechanism enables non-volatile storage of data.
