Abstract: Provided are an operating method of a host device, an operating method of a memory device, and a memory system. The operating method of a host device includes transmitting a request command for performing an eye-opening monitor (EOM) operation to a memory device, transmitting a parameter for performing the EOM operation to the memory device, transmitting pattern data for performing the EOM operation to the memory device, and receiving a first response signal including a result of the EOM operation performed based on the parameter and the pattern data from the memory device.

Abstract: A storage device includes a storage device communicably connected to a host; a nonvolatile memory configured to store calibration data of the host; and a calibration circuit configured to receive a descriptor from the host including the setting information and update the calibration data with the received setting information.

Abstract: A method of operating a universal flash storage (UFS) device communicating with a UFS host via a link is provided. The method determines in the UFS device whether a warm reset of the link is necessary while the UFS device is communicating with the UFS host via the link. Upon determining that the warm reset of the link is necessary, the UFS device initiates the warm reset of the link.

Abstract: A storage device of a storage system includes a device Direct Memory Access (DMA) configured to calculate a data transfer amount based on size information of data provided to a DMA queue; a command manager configured to receive the data transfer amount from the device DMA and to calculate a transfer speed using a speed mode table; and a device interface configured to transfer the transfer speed to a host.

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: Disclosed is a system for storing information searched on the Internet for a portable audio apparatus, including: a server agent for searching and mining relevant information from more than one site for providing arbitrary information on the wired or wireless Internet, by operating an information exploring robot agent according to searching condition and period set by a user and for extracting text information from mined information by performing a first filtering for the mined information according to searching condition; and a client agent for receiving text information extracted from the server agent, performing a second filtering according to searching condition set by a user, converting text information satisfying searching condition into voice information, and storing information by transmitting information to a portable audio apparatus.

Abstract: A multipurpose learning device having a picture book including a plurality of pages, wherein the pages turned in a top-to-bottom hinged direction instead of a side-to-side hinged direction, a memory unit having audio and video data stored therein, the memory unit being detachably connected to a touch board. A surface of the touch board is declined to a predetermined angle for enabling a user to easily position an electronic pen perpendicular to the touch board. Each sheet of the picture book includes a blank page and a picture page and picture information corresponding to a picture on one of the pages is displayed on a host device, such as a television. A user moves the electronic pen over a blank page which is positioned over the touch board, and a cursor is displayed on the host device at a position corresponding to the position of the electronic pen over the blank page and touch board.
