The word lines are respectively coupled to gate terminals of a row of the flash transistors. The bit lines are respectively coupled to opposite ends of a column of the flash transistors. Band-to-band tunneling current at a selected flash transistor is utilized as read current during a read operation. The BTB tunneling current flows from one of the source/drain terminals of the selected flash transistor to the substrate, rather than flowing from one of the source/drain terminals to the other. As a result, charges stored in multiple programming sites of each flash transistor can be respectively sensed.
