Abstract: According to one embodiment, a memory system receives from a host a first write request including a first block identifier designating a first write destination block to which first write data is to be written. The memory system acquires the first write data from a write buffer temporarily holding write data corresponding to each of the write requests, and writes the first write data to a write destination page in the first write destination block. The memory system releases a region in the write buffer, storing data which is made readable from the first write destination block by writing the first write data to the write destination page. The data made readable is a data of a page in the first write destination block preceding the write destination page.

Abstract: According to one embodiment, a memory system manages a plurality of management tables corresponding to a plurality of first blocks in a nonvolatile memory.

Abstract: According to one embodiment, a method is configured to be used for controlling an electronic device configured to operate an other electronic device, byway of example. The method includes displaying an operational interface for operating the other electronic device on a locked screen displayed in a display of the electronic device under a lock condition configured to restrict at least part of an operation on the electronic device, if it is determined that the electronic device has been connected to a first network corresponding to the other electronic device and the display of the electronic device is activated by an operation of a user.

Abstract: According to one embodiment, an electronic device includes a processor. The processor switches a first program guide on a display to a second program guide. The first program guide includes a plurality of first objects related to a plurality of programs on the first channel. The second program guide includes a plurality of second objects related to a plurality of programs on the second channel. When the second program guide is displayed and when one of the plurality of first objects is selected from the first program guide, at least one of the plurality of programs on the second channel in the second program guide including a broadcast time that overlaps a broadcast time of a program corresponding to the selected first object is displayed visually differently.

Abstract: A storage unit of a relaying apparatus stores first identification information that identifies an SIP terminal and second identification that identifies other SIP terminal which is forecast as a transfer destination of a message. A transmitting-and-receiving unit receives from the SIP terminal a request message that is received before a transfer message to be transferred to other SIP terminal and that includes a processing request concerning communications and the first identification information. An obtaining unit obtains from a storage unit the second identification information corresponding to the first identification information included in the received request message. A connection establishing unit establishes communications between the other SIP terminal of the obtained second identification information and the relaying apparatus.

Abstract: A transfer unit transfers a message between a network and an external terminal. An input unit inputs a user ID for identifying a user.
