Working Principles

The BR93H66RFVT-2CE2 utilizes EEPROM technology, which stores data using electrically isolated floating gate transistors. When data is written, a high voltage is applied to the gate, causing electrons to tunnel through a thin oxide layer and become trapped in the floating gate. This trapped charge represents the stored data. During read operations, the charge on the floating gate is measured, allowing the retrieval of the stored information.
