    • A nonvolatile memory device may include a substrate having a cell region, and a cell device isolation layer on the cell region of the substrate to define a cell active region. A floating gate may include a lower floating gate and an upper floating gate sequentially stacked on the cell active region, and a tunnel insulation pattern may be between the floating gate and the cell active region. A control gate electrode may be on the floating gate, and a blocking insulation pattern may be between the control gate electrode and the floating gate. More particularly, the upper floating gate may include a flat portion on the lower floating gate and a pair of wall portions extending upward from both edges of the flat portion adjacent to the cell device isolation layer. Moreover, a width of an upper portion of a space surrounded by the flat portion and the pair of wall portions may be larger than a width of a lower portion of the space. Related methods are also discussed.
    • 非易失性存储器件可以包括具有单元区域的衬底和在衬底的单元区域上的单元器件隔离层,以限定电池活性区域。 浮置栅极可以包括顺序堆叠在单元有源区上的下浮置栅极和上浮置栅极,并且隧道绝缘图案可以在浮栅和电池有源区之间。 控制栅极电极可以在浮置栅极上,并且阻挡绝缘图案可以在控制栅电极和浮栅之间。 更具体地说,上部浮动栅极可以包括在下部浮动栅极上的平坦部分和从邻近电池器件隔离层的平坦部分的两个边缘向上延伸的一对壁部分。 此外,由平坦部分和一对壁部分围绕的空间的上部的宽度可以大于空间的下部的宽度。 还讨论了相关方法。

    • Disclosed is a buffer-based adaptive media playout method in a receiver side of a network media streaming system. The method includes: calculating a playout interval for playing out a current j-th frame (where j is a natural number) of a received media stream; and playing out the current j-th frame after the calculated playout interval has elapsed from the reception of the current j-th frame. The calculation of the playout interval for playing out the current j-th frame of the received media stream includes: calculating a buffer level of a (j+w)-th frame (where w is a natural number); estimating a playout pause or a playout skip on the basis of the calculated buffer level; and calculating the playout interval for playing out the current j-th frame for the predicted one of the playout pause and the playout skip. According to the above-mentioned structure, it is possible to reduce the amount of temporal distortion, such as the RMSE value of playout discontinuity due to delay or jitter, as compared to the buffer-threshold-based media playout techniques according to the related art.
    • 公开了一种在网络媒体流系统的接收机侧的基于缓冲器的自适应媒体播放方法。 该方法包括:计算用于播放接收到的媒体流的当前第j帧(其中j是自然数)的播出间隔; 并且在从当前第j帧的接收经过计算的播出间隔之后播放当前的第j帧。 用于播放接收的媒体流的当前第j帧的播出间隔的计算包括:计算第(j + w)个帧(其中w是自然数)的缓冲器电平; 基于所计算的缓冲器级别来估计播出暂停或播出跳过; 以及计算用于播放播放暂停和播放跳过中的预测播放暂停的当前第j帧的播出间隔。 根据上述结构,与根据现有技术的基于缓冲器阈值的媒体播放技术相比,可以减少时间失真的量,诸如由于延迟或抖动引起的播出不连续性的RMSE值 。
