    摘要: A three-dimensional semiconductor device may comprise a first cell region, a second cell region, and a via plug region disposed between the first cell region and the second cell region; a word line stack disposed in the first cell region, the via plug region, and the second cell region, the word line stack including a plurality of word lines and a plurality of interlayer insulating layers which are alternately stacked; and a plurality of via plugs exclusively connected to the plurality of the word lines, respectively, by vertically penetrating through the word line stack in the via plug region. The via plugs may have an arrangement of a zigzag pattern in a row direction from a top view. The diameters of the via plugs may increase in the row direction.

    摘要: Disclosed is a semiconductor device having a memory cell which comprises a transistor having a control gate and a storage gate. The storage gate comprises an oxide semiconductor and is able to be a conductor and an insulator depending on the potential of the storage gate and the potential of the control gate. Data is written by setting the potential of the control gate to allow the storage gate to be a conductor, supplying a potential of data to be stored to the storage gate, and setting the potential of the control gate to allow the storage gate to be an insulator. Data is read by supplying a potential for reading to a read signal line connected to one of a source and a drain of the transistor and detecting the change in potential of a bit line connected to the other of the source and the drain.
