A memory system includes a memory device configured to store a piece of data in a location which is distinguished by a physical address and a controller configured to generate a piece of map data associating a logical address, inputted along with a request from an external device, with the physical address and to transfer a response including the piece of map data to the external device.

Memory system for utilizing a memory included in an external device

A method for controlling temperature of a memory system which includes a memory device suitable for storing memory map data including a logical address of an external device and a physical address of a memory device, corresponding to the logical address; and a controller suitable for downloading at least a part of the memory map data and storing and managing the downloaded data as controller map data, and uploading at least a part of the controller map data to the external device, the method comprising: measuring temperature of the memory device; and performing a map downloading for the memory map data from the memory device in response to the measured temperature.

Memory system and method of controlling temperature thereof

A memory system includes a memory device comprising a memory block having a plurality of pages; and a controller suitable for receiving from an external device an erase request for an erase operation and a first logical address relating to the erase request, and correlating the first logical address to erase information.

Memory system and method for performing command operation by memory system

A memory system includes a memory device and a controller. The memory device stores a piece of data in a location which is distinguished by a physical address. The controller generates map data, each piece of map data associating a logical address, inputted along with a request from an external device, with the physical address, selects a piece of map data among the map data based on a status regarding the piece of map data, and transfers selected map data to the external device.

An electronic device according to an embodiment of the present invention comprises: a universal serial bus (USB) interface; a processor electrically connected to the USB interface; and a memory electrically connected to the processor, wherein the memory may store instructions configured to, when executed, cause the processor to: enter a security mode; in the security mode, receive, from an external device connected to the electronic device via the USB interface, a USB class code corresponding to the external device; determine whether the USB class code is included in a white list of connectable devices allowed to be connected to the electronic device in the security mode; and control a communication connection between the external device and the electronic device according to whether the USB class code is included in the white list. Other embodiments are also possible.

Method for establishing connection to external device via USB interface, and electronic device therefor

A memory system may include a memory device comprising a plurality of memory blocks and a controller suitable for controlling an operation of the memory device. The controller may perform a fake operation on a predetermined memory block not used to store data when a temperature of the memory device is in a low temperature range.

Memory system and method of controlling operations on bad memory block based on temperature

A memory system includes: a sudden power off (SPO) frequency value calculator suitable for determining a SPO frequency value; a checkpointing mode controller suitable for setting the memory system to one among a high frequency checkpointing mode and a low frequency checkpointing mode according to the SPO frequency value; and a processor suitable for performing a checkpointing operation according to the set frequency checkpointing mode.

Memory system and operating method of the same

A recording medium on which copyright information is recorded, and an apparatus and method therefor. The recording medium contains remake content made using at least one original content, original copyright information on the original content, and remake copyright information on the remake content. According to the recording medium and the apparatus and method therefor, the copyright of original content is protected and the personal user right of an individual user on the original content is guaranteed.

Recording medium containing copyright information, recording apparatus and recording method therefor

An apparatus for and method of embedding a watermark into original information, transmitting the watermarked information, and reconstructing the watermark from the transmitted watermarked information include embedding a portion of a plurality of components constituting the watermark into the original information, and using the remaining portion of the components as keys for reconstructing the watermark. According to the method, since a size of data to be embedded is greatly reduced, degradation of the watermarked information is prevented, and the information becomes more robust against hacking attacks or errors occurring in a variety of ways when transmitting the information.

Apparatus for and method of embedding watermark into original information, transmitting watermarked information, and reconstructing the watermark

An information storage medium containing multi-language markup document information, and an apparatus for and a method of reproducing the information storage medium which includes audio/video (AV) data, multiple markup documents which contain text information to be displayed in a selected language with a video picture decoded and reproduced from the AV data, and multi-language markup document information for designating one of the multiple markup documents as a markup document in the selected language. Accordingly, the information storage medium allows the reproducing apparatus to display the text information included in the markup document in the interactive mode in respective multiple languages.
