    • In a semiconductor memory device and method, phase-change memory cells are provided, each including a plurality of control transistors formed on different layers and variable resistance devices formed of a phase-change material. Each phase-change memory cell includes a plurality of control transistors formed on different layers, and a variable resistance device formed of a phase-change material. In one example, the number of the control transistors is two. The semiconductor memory device includes a global bit line; a plurality of local bit lines connected to or disconnected from the global bit line via local bit line selection circuits which correspond to the local bit lines, respectively; and a plurality of phase-change memory cell groups storing data while being connected to the local bit lines, respectively. Each of the phase-change memory cells of each of the phase-change memory cell groups comprises a plurality of control transistors formed on different layers, and a variable resistance device formed of a phase-change material. In addition, the semiconductor memory device has a hierarchical bit line structure that uses a global bit line and local bit lines. Accordingly, it is possible to increase both the integration density of the semiconductor memory device and the amount of current flowing through each of the phase-change memory cells.
    • 在半导体存储器件和方法中,提供了相变存储单元,每个都包括形成在不同层上的多个控制晶体管和由相变材料形成的可变电阻器件。 每个相变存储单元包括形成在不同层上的多个控制晶体管和由相变材料形成的可变电阻器件。 在一个示例中,控制晶体管的数量是两个。 半导体存储器件包括全局位线; 通过分别对应于本地位线的本地位线选择电路分别连接到全局位线或与全局位线断开的多个局部位线; 以及分别在连接到本地位线时存储数据的多个相变存储单元组。 每个相变存储单元组的每个相变存储单元包括形成在不同层上的多个控制晶体管和由相变材料形成的可变电阻器件。 此外,半导体存储器件具有使用全局位线和局部位线的分层位线结构。 因此,可以增加半导体存储器件的集成密度和流过每个相变存储单元的电流量。

    • A stent inserting device is used in inserting a self-expandable stent with leading and trailing ends into a tubular organ of a living body. The stent inserting device includes a grip body, an external tube attached to a front end of the grip body, a push member movably inserted into the external tube from a rear end of the grip body, and a tubular cap for removably receiving the stent in a compressed state. The tubular cap has a front end operatively connected to the push member and a rear end slidably fitted to a front end of the external tube. The stent inserting device is designed to hold the stent within the tubular cap in such a manner that the stent is first expanded at the trailing end and then gradually expanded toward the leading end when the tubular cap is pushed away from the external tube.
    • 支架插入装置用于将具有前端和后端的自扩张支架插入活体的管状器官中。 所述支架插入装置包括握持体,附接到所述把手本体的前端的外部管,从所述把手主体的后端可移动地插入到所述外部管中的推动构件,以及用于将所述支架可拆卸地接收的管状帽 压缩状态。 管状帽具有可操作地连接到推动构件的前端和可滑动地装配到外部管的前端的后端。 支架插入装置被设计成将支架保持在管状帽内,使得支架首先在后端膨胀,然后当管状帽被推离外管时朝向前端逐渐膨胀。
