Working Principles

AT49F001-70JI utilizes a floating gate transistor technology to store and retrieve digital information. The memory cells consist of transistors that can be electrically programmed and erased. When data is written, charges are trapped in the floating gate, altering the transistor's behavior. These charges can be removed during the erase cycle, resetting the transistor to its original state.
