  • Patent number: 10381410
    Abstract: An electronic device includes a semiconductor memory that includes: first and second lines spaced apart from each other and crossing each other; a third line spaced apart from the second line and crossing the second line; a first variable resistance element interposed between the first and second lines and overlapping an intersection of the first and second lines; a second variable resistance element interposed between the second and third lines and overlapping an intersection of the second and third lines, a part of the second variable resistance element generating a greater amount of heat than a part of the first variable resistance element when a current flows through the first variable resistance element in an opposite direction to a current flowing through the second variable resistance element; and a material layer serially connected with the second variable resistance element, disposed between the second and third lines, and exhibiting electrical resistance.

  • Patent number: 7338864
    Abstract: Disclosed are a memory device and a method for fabricating the same. The memory device includes: a substrate provided with a trench; a bit line contact junction formed beneath the trench; a plurality of storage node contact junctions formed outside the trench; and a plurality of gate structures each being formed on the substrate disposed between the bit line contact junction and one of the storage node contact junctions. Each sidewall of the trench becomes a part of the individual channels and thus, channel lengths of the transistors in the cell region become elongated. Accordingly, the storage node contact junctions have a decreased level of leakage currents, thereby increasing data retention time.
