Abstract: A memory controller operating method includes executing a read operation directed to read data including a correctable data unit and an uncorrectable data unit, the uncorrectable data unit containing data that is uncorrectable using a normal error correction operation. The method further including; performing the normal error correction operation on the correctable data unit to generate partial read data, communicating dummy data instead of the uncorrectable data unit along with the partial read data from the memory controller to a host, and performing an enhanced error correction operation on the uncorrectable data unit while at least in part the dummy data and partial data are being communicated from the memory controller to the host.

Abstract: A storage device that includes a nonvolatile memory device is described. The storage device includes areas and a controller. The controller receives a write command and data from an external host device. The controller then preferentially writes the data in an area associated with a turbo write based on a turbo write policy, or in an area not associated with a turbo write based on a normal write policy. The controller also receives a move command from the external host device and moves data stored in the area to a different area based on the move command.

Abstract: A storage system according to an exemplary embodiment of the inventive concept includes a host and a storage device. The host includes a link speed table having data transfer speed information for an application. A data transfer speed manager is configured to calculate a predetermined transfer speed based on the data transfer speed information for the application. A device driver is configured to control an operation of the storage device. A host controller is configured to change a data transfer speed of an interface based on the predetermined transfer speed provided through the device driver.

Abstract: A storage device includes a nonvolatile memory device that includes a first region including memory cells configured to store n-bit data and a second region including memory cells configured to store m-bit data and a memory controller, where n and m are natural numbers and n is less than m. The first region includes a first area and a second area, and the second region includes a third area. The memory controller is configured to perform one of a turbo write operation on the first area or the second area and a normal write operation on the third area, and configured to perform one of a turbo read operation on the first area or the second area and a normal read operation on the third area.

Abstract: An operation method is for a storage device that includes a storing unit storing a plurality of error logs and a physical layer and exchanges an electrical signal with a host via the physical layer. The operation method includes receiving a debugging command from the host, setting a first value at a first attribute included in the physical layer in response to the debugging command, setting a second value different from the first value at the first attribute in response to a control of the host, setting one among the plurality of error logs at a second attribute based on the first attribute at which the second value is set, and transmitting the error log set at the second attribute to the host in response to a control of the host.
