  • Patent number: 10192624
    Abstract: A non-volatile memory device may include a memory cell array including a plurality of planes, a page buffer connected to the memory cell array and corresponding to each of the plurality of planes, and a decoupling circuit. The page buffer is configured to receive a bit line voltage control signal (BLSHF) via a first node. The decoupling circuit is connected to the first node. The decoupling circuit includes at least one decoupling capacitor configured to execute charge sharing via the first node.

  • Patent number: 9645169
    Abstract: A measurement method in which a sensing unit acquires surface data of a measurement target while scanning the surface of the measurement target and at least one of the sensing unit and the measurement target is moved in order for the sensing unit to scan the surface along a plurality of fast scan lines on the surface of the measurement target, includes: a first step in which the sensing unit scans a surface along any one fast scan line of the plurality of fast scan lines to acquire the surface data along the any one fast scan line; and a second step in which the sensing unit acquires a surface data along a fast scan line most adjacent to the any one fast scan line while at least one of the sensing unit and the measurement target is moved along the most adjacent fast scan line, after the first step.

  • Patent number: 8767475
    Abstract: In method of programming a nonvolatile memory device, multi-bit data are loaded into a plurality of page buffers. Multi-level cells included in a multi-level cell block are programmed to a plurality of intermediate program states including a first intermediate program state and a second intermediate program state which is higher than the first intermediate program state based on the multi-bit data. Whether the multi-level cells are programmed to the plurality of intermediate program states is verified. Cell group information for the first intermediate program state is generated by checking whether a result of the verification for the second intermediate program state satisfies a predetermined criterion. The multi-level cells are programmed to a plurality of target program states corresponding to the multi-bit data based on the cell group information.
