Working Principles

The AT93C86-10SC-2.7 EEPROM chip utilizes a floating gate transistor structure to store data. The data is programmed by applying a high voltage to the gate, which traps charge in the floating gate. This trapped charge represents a logical "1" or "0". The data can be erased by applying a higher voltage to remove the trapped charge. During read operations, the stored charge is sensed to determine the logic level.
