Working Principles

The 93LC46BT-E/OT is based on EEPROM technology, which utilizes floating gate transistors to store and retrieve data. When data needs to be written, a high voltage is applied to the gate of the transistor, trapping electrons in the floating gate. This alters the threshold voltage of the transistor, representing a binary value (0 or 1). To read the data, the threshold voltage is measured, allowing the stored information to be retrieved.
