Working Principles

The 93C86B-E/MS is based on EEPROM technology, which utilizes floating gate transistors to store and retrieve data. When data needs to be written, a high voltage is applied to the gate, allowing electrons to tunnel through an insulating layer onto the floating gate. This process traps the charge, representing a binary value. To read the data, the stored charge is measured, determining the logic state.
