  • Publication number: 20130110794
    Abstract: An apparatus and method for stably filtering duplicate data in various resource-restricted environments such as a mobile device and medical equipment are provided. The apparatus includes a cell array unit configured to comprise one or more cells; a duplication check unit configured to check whether input data is duplicate and set a value of a cell that matches the input data; and a duplication probability calculation unit configured to, in response to the input data being determined as duplicate data by the duplication check unit, calculate a probability of duplication of the input data using the set value of the cell. Data which may be duplicate data among a large amount of input data is not arbitrarily deleted, but is provided to an application along with a probability of duplication of the data. Accordingly, a false positive error that occurs in Bloom filter is prevented, and thereby system stability can be improved.

  • Patent number: 8207566
    Abstract: A vertical channel transistor includes a plurality of active pillar patterns extending perpendicularly from the top surface of the substrate toward an upper part. A gate insulating layer is deposited on the side wall of the active pillar pattern and serves as an ion diffusion barrier between the pillar patterns and surrounding lower gate electrodes. The resultant pillar pattern structure is encapsulated with a metal. The resultant pillar pattern is surrounded on all sides by a specified height by a sacrificial layer of Spin-On Dielectric (SOD). The metal layer is etched-back to the height of the sacrificial layer, thus forming the lower gate electrodes. A spacer layer of an insulating mater is deposited surrounding the upper part of the pillar patterns and the sacrificial layer is removed exposing a part of the lower gate electrodes. The exposed gate electrode is etched to facilitate semiconductor integration.
