Working Principles

The 93C86B-E/ST is based on EEPROM technology, which utilizes floating-gate transistors to store and retrieve data. When data needs to be written, an electrical charge is applied to the floating gate, altering its threshold voltage. This change in voltage represents the stored data. To read the data, the threshold voltage is measured and interpreted as either a logic high or low.
