  • Patent number: 12035532
    Abstract: A memory array and a structure of the memory array are provided. The memory array includes flash transistors, word lines and bit lines. The flash transistors are arranged in columns and rows. The flash transistors in each column are in serial connection with one another. 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.
