    摘要: A semiconductor memory device includes memory cells, a memory cell array, bit lines, source lines, word lines, and select gate lines. Each of the memory cells includes a first MOS transistor having a floating gate and a control gate and a second MOS transistor having a stacked gate including a first gate electrode and a second gate electrode formed above the first gate electrode and having its drain connected to the source of the first MOS transistor. Each of the bit lines electrically connects the drains of the first MOS transistors in a same column. Each of the word lines connects the control gates of the first MOS transistors in a same row. Each of the select gate lines electrically connects the second gate electrodes of the second MOS transistors in a same row and is electrically isolated from the second gate electrodes.
