Working Principles

The 93C76AT-E/ST EEPROM utilizes a floating gate transistor structure to store digital information. When data is written, an electric charge is trapped in the floating gate, altering the transistor's threshold voltage. This change in threshold voltage determines whether the transistor represents a logical "0" or "1". The stored data can be read by applying appropriate voltages to the memory cells.
