Abstract: According to an embodiment, when receiving a read request designating a logical address range of a particular size or more from a host, a first circuit issues a plurality of first sub-commands, each of which is a sub-command for each first data unit, in order of logical addresses. A second circuit respectively adds serial numbers corresponding to the plurality of first sub-commands in the order of issuance. A plurality of third circuits respectively executes processing of specifying locations of the first data unit based on management information for the plurality of first sub-commands in a distributed manner. A fifth circuit reorders the plurality of first sub-commands in the logical address order based on the serial numbers after the processing by the plurality of third circuits. A sixth circuit executes a read operation on a first memory based on the plurality of first sub-commands reordered in the order of logical addresses.

Abstract: According to one embodiment, a video display device includes an HDMI interface which transfers video information and control commands to and from a video output device connected thereto. The video display device further includes a video display module having one or more display areas to display external video and/or internal video, and a notification module which notifies resolution information for the display areas to the video output device using the control commands when the video display module simultaneously displays multiple videos including the external video.
