Working Principles

The S29AL008J55BFIR20 flash memory utilizes a floating gate transistor technology. It stores data by trapping electric charge in the floating gate, which alters the transistor's conductive properties. This trapped charge can be erased or programmed using specific voltage levels applied to the control inputs.

During read operations, the addressed memory location is accessed, and the stored data is retrieved by sensing the transistor's conductive state. Write operations involve erasing the targeted memory sectors and then programming new data into them.
