Abstract: A memory system includes a first non-volatile memory and a control circuit. The first non-volatile memory operates in one of a plurality of operation modes including at least a first operation mode and a second operation mode. The control circuit switches the operation mode of the first non-volatile memory based on an operation mode switching information received from an external device.

Abstract: According to one embodiment, a memory device includes a non-volatile first memory, a non-volatile second memory, a first controller, and a second controller as one example. The first controller writes, upon receipt of control information by a communication unit, the control information to the first memory. The control information defines an operation regarding a data file stored in the second memory. The second controller executes the control information after a start of the memory device.

Abstract: According to an embodiment, a memory device includes a nonvolatile first memory, a nonvolatile second memory, a first controller, and a second controller. The first controller is configured to write, to the first memory, data received over a short-range radio communication by using power generated in the short-range radio communication. The second controller is configured to execute, at a startup of the memory device, a transfer process of reading a file written in the first memory and storing the read file to the second memory.

Abstract: According to an embodiment, a memory device includes: a first controller configured to register, to a first memory, access restriction information received over a short-range radio communication by using power generated in the short-range radio communication; and a second controller configured to, at a startup of the memory device, read the access restriction information registered in the first memory and perform an access restriction to a file stored in a second memory based on the read access restriction information.

Abstract: According to one embodiment, to discriminate an optical disk having a DISCID.DAT file existing under an ADV_OBJ folder as compatible with an advanced standard, and discriminate a system of a video content by reading out system identification information (TV system) existing in a VTSI file under a TS folder of a high-density optical disk standard with respect to the optical disk. In case a video content reproduction device can reproduce a video content of the system, a reproduction processing sequence with respect to the optical disk compatible with the advanced standard is started.

Abstract: According to one embodiment, an information recording medium playback apparatus of the invention comprises an interrupt specifying section, an interrupt position information holding section, a playback resume specifying section which gives a playback resume instruction after the interruption, an interrupt position read control section which, when the playback resume instruction has been given, reads a specific management information pack at the interrupt position on the basis of the interrupt position information, a synchronous information referring section which refers to synchronous information included in the management information pack, a specific pack taking-in control section which takes in a specific pack from a position ahead of the interrupt position, referring to the synchronous information, and a playback processing section which reproduces not only the data in the specific pack but also the data in the pack from the interrupt position.
