Working Principles

The 93LC46BT-E/SN operates based on the principles of EEPROM technology. It 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 behavior. This change can be detected during subsequent read operations. The stored data remains intact even when power is disconnected.
