  • Publication number: 20230236964
    Abstract: Disclosed is a method of operating a storage controller, the storage controller communicating with a host and a non-volatile memory device. The method includes receiving a first erase request from the host, the first erase request being for a first zone of a plurality of zones of the non-volatile memory device, loading first allocation list information of the first zone from an allocation list table based on the first erase request, deallocating memory blocks allocated to the first zone based on the first allocation list information, wherein sequential physical page numbers of the memory blocks are respectively mapped onto sequential logical page numbers, and providing the non-volatile memory device with a physical erase request for the deallocated memory blocks of the first zone.

  • Patent number: 10860455
    Abstract: A storage device and a method of operating the storage device are provided. The storage device includes a non-volatile memory including a plurality of non-volatile memory cells, a processor configured to control an operation of storing data received from a host in the non-volatile memory, a host interface configured to transmit and receive the data and control signals to and from the host, and a trace module. The trace module is configured to generate trace data for the processor or the host interface during an operation of the processor or the host interface and the trace module is configured to provide the trace data to the non-volatile memory.

  • Patent number: 9805799
    Abstract: A nonvolatile memory device includes a first area of single-level cells (SLCs) and a second area of multi-level cells (MLCs). The device determines whether a free block can be created by copying data between memory blocks of the first area. Upon determining that the free memory block can be created by copying data between the memory blocks of the first area, the device copies the data between the memory blocks of the first area to create the free memory block. Otherwise, the device selects at least one memory block from the first area and allocates the selected memory block as free memory block by copying the data stored in the selected memory block of the first area to the second area.

  • Patent number: 8069488
    Abstract: A method and apparatus exclusively control a device in a home network. A control point requests exclusive control authority from the device. In response to the request the control point receives an identifier (RID) used to successfully authenticate the exclusive control authority. The control point then acquires the exclusive control authority and controls the device. Accordingly, it is possible to prevent other control points from interfering with the device so as not to perform an operation which is not desirable for the control point that acquires the exclusive control authority over the device.

  • Patent number: 7970806
    Abstract: Management of files in a memory, such as a flash memory, includes storing in the memory a first node including a first type of metadata of the file, a second node including data of the file and a third node including a second type of metadata of the file including file status and memory location information for the first and second nodes. The third node may include a node including memory location information for the second node and a node including an index table that cross-references a memory location for the memory location information for the second node to a memory location of the first node. Methods and devices may be provided.
