  • Patent number: 11075299
    Abstract: Embodiments of the invention are directed to a method that includes forming a fin over a major surface of a substrate. The fin includes an active fin region having a top fin surface and a fin sidewall. The top fin surface is substantially parallel with respect to the major surface, and the fin sidewall is substantially perpendicular with respect to the major surface. A gate is formed over and around a central portion of the fin, the gate having a bottom gate region and a top gate region. The bottom gate region is substantially below the top fin surface and includes a bottom gate region sidewall that is substantially parallel with respect to the fin sidewall. The top gate region is substantially above the top fin surface and includes a top gate region sidewall that is at an angle with respect to the major surface.

  • Patent number: 10936560
    Abstract: Embodiments of the present disclosure disclose methods and devices of data de-duplication. The method of data de-duplication performed at a client comprises: in response to receiving data to be backed up at a client, sampling the data to be backed up to obtain the sampled data; generating a signature for the sampled data; transmitting the signature to a master storage node in a storage cluster including a plurality of storage nodes, to allow the master storage node to select one storage node from the plurality of storage nodes; receiving an indication of the selected storage node from the master storage node; and transmitting, based on the indication, the data to be backed up to the selected storage node. Embodiments of the present disclosure also provide methods of data de-duplication performed at the master storage node and the slave storage node, and corresponding devices.

  • Publication number: 20200012440
    Abstract: There is provided a method and device for data replication. The method comprises: obtaining, in a network interface card, data segments by segmenting input first data; determining, in the network interface card, fingerprints corresponding to the data segments; and comparing, in a central processing unit, the fingerprints of the data segments with existing fingerprints corresponding to processed data segments, and determining, based on a result of the comparing, whether to de-duplicate the data segments corresponding to the fingerprints, to perform the data replication.
