Working Principles

The 93C76A-E/MS EEPROM utilizes a floating gate transistor structure to store and retrieve data. When data is written, an electric charge is trapped in the floating gate, altering the transistor's threshold voltage. This change allows the stored data to be read back accurately. The data can be erased by applying a higher voltage to remove the trapped charge from the floating gate.
