Abstract: An electronic device and a method of controlling the same are provided. The electronic device includes a new memory configured to include a main memory region and a file system region and a processor configured to perform computing and perform checkpointing on the main memory region and the file system region depending on a predetermined condition, wherein the main memory region includes a checkpoint table to which information on a page in which data are changed is written, and the processor initializes the checkpoint table and sets an attribute of pages of the main memory region to read-only at the time of performing the checkpointing on the main memory region.

Abstract: Provided is a control device for managing a plurality of memory channels driven through multichannel interleaving. The apparatus includes a stripe configuring unit for configuring a stripe according to a physical number of pages included in the plurality of memory channels, and a parity generating unit for generating parity data on the configured stripe.

Abstract: Provided is a computing system and method that utilizes a non-volatile random access memory (NVRAM). A system including the NVRAM as a part of a memory or a whole memory may execute a program in the NVRAM, and, when the system is re-operated after being shut down, may restore a state and data of the program being executed in the NVRAM to an original state and thus, may provide a permanent computing environment.

Abstract: Disclosed is a data processing system and method. The data processing system may include a plurality of servers to process data, and a controller to shut off a power supplied to a server, among the plurality of servers, having data throughput less than a predetermined data throughput.

Abstract: A flash memory management method is provided. According to the method, when a request to write the predetermined data to a page to which data has been written is made, the predetermined data is written to a log block corresponding to a data block containing the page. When a request to write the predetermined data to the page again is received, the predetermined data is written to an empty free page in the log block. Even if the same page is requested to be continuously written to, the management method allows this to be processed in one log block, thereby improving the effectiveness in the use of flash memory resources.
