  • Patent number: 11587947
    Abstract: In a 3D semiconductor memory device, a stack structure includes electrodes and first insulating layers disposed between the electrodes. The stack structure has a stair structure on a connection region. A vertical channel structure penetrates the stack structure on a cell array region. A vertical dummy structure penates the stair structure on the connection region. A second insulating layer is selectively disposed on the cell array region. A maximum thickness of the second insulating layer ranges from 1.5 times to 10 times a maximum thickness of the first insulating layer on the second insulating layer. The vertical channel structure includes an abrupt diameter change at a level of a top surface of the second insulating layer. The abrupt diameter change has a surface which is parallel to the top surface of the second insulating layer and is substantially coplanar with the top surface of the second insulating layer.

  • Patent number: 10111121
    Abstract: Various embodiments manage service issues within a wireless communication network. In one embodiment, a one or more call detail records associated with a set of wireless communication devices of a wireless communication network is received. A set of information within each of the one or more call detail records is compared to a baseline statistical model. The baseline statistical model identifies a normal operating state of the wireless communication network. At least one outlier call detail record in the one or more call detail records is identified based on the comparison. The at least one outlier call detail record indicates that at least one wireless communication device associated with the at least one outlier call detail record experienced one or more service issues.
