Patent number: 11404438Abstract: A memory device includes a substrate; and a stack structure, including alternately arranged first dielectric layers and electrode layers. In a first lateral direction, the memory device includes array regions and a staircase region arranged between array regions. In a second lateral direction, the stack structure includes a first block and a second block, each including a wall-structure region and extending along the first lateral direction. The wall-structure regions of the first block and the second block are adjacent to each other and together form a wall structure in the staircase region. The memory device also includes a first separation structure, formed through the stack structure and positioned between the first block and the second block in array regions along the first lateral direction; and second dielectric layers positioned between the first block and the second block in the staircase region, and alternated with the first dielectric layers.Type: GrantFiled: September 4, 2020Date of Patent: August 2, 2022Assignee: Yangtze Memory Technologies Co., Ltd.Inventors: Kai Han, Yali Guo, Zhipeng Wu, Lu Zhang, Hang Yin, Simin Liu, Bo Xu

Patent number: 10895953Abstract: The present application provides internet browsing especially a three dimensional webpage browsing methods and systems by using the movement of a computing device with a display. By moving the computing device, a user changes the location and the orientation of the computing device, and thus interacts with at least one information item in a first web page. The computing device measures the location difference and the orientation difference between the computing device and the information item, and determines whether each of the location difference and the orientation difference is within a threshold, respectively. If both the location and orientation differences are within the threshold for a predetermined time, the user is directed to a second web page.Type: GrantFiled: August 19, 2019Date of Patent: January 19, 2021Assignee: TENCENT TECHNOLOGY (SHENZHEN) COMPANY LIMITEDInventors: Simin Liu, Jianxin Huang, Liang Guo
