Abstract:
PURPOSE: A non-volatile memory device and a programming method thereof reduce program disturbance and secure a pass voltage window by determining a program order considering the size of a channel hole of a cell string. CONSTITUTION: A page buffer circuit (130) is connected to bit lines of a memory cell array. A row decoder (120) is connected to the memory cell array through word lines and selection lines. The row decoder transmits a word line voltage to program a first memory cell first before a second memory cell among multiple memory cells in a program operation. The first memory cell is placed over the second memory cell based on a substrate. The diameter of a channel hole of the first memory cell is larger than the diameter of a channel hole of the second memory cell.

PURPOSE: A predictive structure for the point conversion based multi-view video encoding method and an apparatus thereof, and a predictive structure for the point conversion based multi-view video decoding method and an apparatus thereof are provided to perform the prediction between the videos in the generated additional point video stream even when the anchor picture right before the point, where the point conversion generated, does not exists, by not referring to the videos of the point conversion section which is restored before the point conversion section where the current video is included, in prediction of the videos of the additional point videos. CONSTITUTION: A multi-view video decoding device restores the basis point videos through the motion compensation referring to the basis point videos (S25). The device performs the variation compensation, which refers to at least one among the restored basis point videos, toward the video stream of a first additional point among the additional point video streams, thereby restoring the point renewal video in which the point conversion of the first additional point is available (S27). The device performs at least one of the variation compensation, referring to the basis point video toward the video stream of the first additional point, and the motion compensation, referring to the identical point videos, thereby restoring the first additional point videos, not the point renewal video (S29).

PURPOSE: A method and an apparatus for parallel entropy-encoding, and a method and an apparatus for parallel entropy-decoding are provided to initialize internal state information of a bitstream buffer after entropy-encoding the last block in each row of blocks, thereby skipping decision about initialization probability. CONSTITUTION: A first entropy-encoding unit sequentially performs entropy-encoding of a horizontal sequence of blocks that forms a first row of blocks (S13).

After completing entropy-encoding of the last blocks in the first row of blocks, the first entropy-encoding unit initializes internal state information of the last entropy-encoded bitstream of the first row of blocks (S17).
