Working Principles

The AT29C020-12JI utilizes flash memory technology to store and retrieve digital information. It employs a combination of floating-gate transistors and control circuitry to enable non-volatile storage. When data is written, charges are trapped in the floating gate, altering the transistor's behavior. This alteration allows the stored data to be retained even when power is removed. During read operations, the control circuitry retrieves the stored charges and interprets them as digital information.
