Working Principles

The 93AA46X/SN operates based on the principles of EEPROM technology. It utilizes a floating gate transistor structure to store and retrieve data. The data is written by applying a high voltage to the gate, which traps charge in the floating gate, representing a logical "1" or "0". The stored data can be read by sensing the voltage level on the gate.
