    摘要： In a method of operating a storage device including a non-volatile memory (NVM), the non-volatile memory including a memory cell array, the memory cell array including a first plane and a second plane, the method includes receiving a read command set for data sensing of the first and second plane; simultaneously loading first page data stored in the first plane into a first page buffer of the first plane and second page data stored in the second plane into a second page buffer of the second plane based on the read command set; receiving a data output command set that includes the first plane; and continuously transmitting the first page data and the second page databased on the data output command set.

    摘要： A data storage device includes a nonvolatile memory device, a storage controller and a mapping controller. The nonvolatile memory device stores an execution code that controls operations of the data storage device. The storage controller uploads and stores the execution code from the nonvolatile memory device to a host memory buffer included in an external host device, and downloads the execution code in realtime from the host memory buffer to execute the execution code that is downloaded from the host memory buffer. The mapping controller manages a mapping table including mapping relations between the execution code and host addresses of the host memory buffer at which the execution code is stored. A speed of accessing the execution code is increased and performance of the data storage device is enhanced by using the host memory buffer as storage of the execution code to control the operation of the data storage device.

    摘要： A memory device includes a nonvolatile memory having a first block and a memory controller configured to exchange data with the nonvolatile memory. The memory controller includes a first processor to divide the first block into first and second domains, a second processor to generate a reclaim signal by determining whether to perform reclaiming on each of the first and second domains and a third processor performer which reclaims each of the first and second domains according to the reclaim signal and merges the first and second domains.

    摘要： A redundant array of independent disks (RAID) storage device including; a memory device including first memory devices configured to store at least one of data chunks and corresponding parity (data chunks/parity) and a second memory device configured to serve as a spare memory region, and a RAID controller including a RAID internal memory configured to store a count table and configured to control performing of a rebuild operation in response to a command received from a host, wherein upon identification of a failed first memory device, the RAID controller accesses used regions of non-failed first memory devices based on the count table and rebuilds data of the failed first memory device using the second memory device.

    摘要： A storage device includes a nonvolatile memory device and a controller that accesses the nonvolatile memory device based on a request of an external host device, receives a first clock signal from the external host device, generates a second clock signal through frequency multiplication of the first clock signal, and communicates with the external host device based on the second clock signal. The controller requests the external host device to adjust a multiplication ratio for the frequency multiplication of the first clock signal.

    摘要： A system includes a transmission device and a reception device that are connected through a link. The reception device includes a reception buffer configured to receive and store transaction layer packets and a reception flow controller configured to generate flow control packets by monitoring an occupation state of the reception buffer. The transmission device includes a transmission buffer, a transmission flow controller and a dynamic frequency controller. The transmission buffer stores pending transaction layer packets to be transferred to the reception device. The transmission flow controller controls a flow of transaction layer packets to be transferred to the reception device based on the flow control packets received from the reception device. The dynamic frequency controller controls a frequency of an internal clock signal of the transmission device by monitoring a state of the transmission buffer and a state of the transmission flow controller.
