  • Patent number: 11644992
    Abstract: A storage system performing data deduplication includes a storage device configured to store data received from a host, and a controller configured to receive the data and an index associated with the data received from the host. The controller includes a memory configured to store mapping information and a reference count, the mapping information associating the index received from the host with a physical address of the storage system, the reference count associated with the index received from the host. The controller determines whether the data received from the host corresponds to a duplicate of data previously stored in the storage device by reading, from the memory, the mapping information and the reference count, the reading based on the index received from the host. The controller performs a deduplication process by updating the reference count if the data received from the host corresponds to the duplicate of data previously stored.

  • Publication number: 20230099713
    Abstract: Disclosed is a method for manufacturing a dry electrode. In the method, a conductive primer layer and an insulating protective layer are formed in a single step, or the insulating protective layer is formed first before an electrode active material layer is formed and after the conductive primer layer is formed. In this manner, there is no gap between the insulating protective layer and the conductive primer layer, thereby providing further improved insulation property. In addition, since the dry electrode is manufactured by laminating the current collector having the conductive primer layer and the insulating protective layer with the dry electrode film, an electrode having excellent adhesion and improved stability can be obtained advantageously.
