Working Principles

The 93AA46C-I/P is based on EEPROM technology, which utilizes floating-gate transistors to store digital information. When data needs to be written, an electrical charge is applied to the floating gate, altering its threshold voltage. This change in voltage represents a binary value (0 or 1). To read the stored data, the threshold voltage is measured, allowing the retrieval of the stored information.
