    摘要: A method of managing data in a system including a nonvolatile memory includes storing a root object of application data, and at least one sub object referenced by the root object in the nonvolatile memory, and mapping virtual addresses of the root object and sub object to physical addresses of the nonvolatile memory respectively, in a page unit. The root object stored in the nonvolatile memory includes a pointer that references the sub object stored in the nonvolatile memory.

    摘要: A phase change memory device includes a memory cell array, a register unit and a control unit. The memory cell array includes a plurality of phase change memory cells. The register unit includes a circular queue. The control unit receives a write address and a write data in a write mode, programs the write data in a phase change memory cell corresponding to the write address among the plurality of phase change memory cells, provides the write address and the write data to the register unit, and outputs a write complete signal before a phase of the phase change memory cell is stabilized or after the phase of the phase change memory cell is stabilized based on a logic level of a first result signal received from the register unit. The phase change memory device increases a programming speed.

    摘要: A method and apparatus for allocating disc space for recording files, the method including: detecting one or more first sets, each comprising one or more empty sections of the disc that are larger than a predetermined reference value; detecting one or more second sets, each comprising one or more empty sections that are equal to or larger than a size of the data when combined; and allocating, to the data, an optimum set that results in a shortest seek time from a predetermined reference point. Accordingly, it is possible to effectively allocate empty disc space in consideration of both the distances of empty disc sections to a reference point and seek time, thus reducing the time taken to seek target data compared to methods of allocating disc space that only consider the distances of empty disc sections to a reference point.

    摘要: A device includes a memory controller, a memory bus coupled to the memory controller, an internal memory and an external memory connection unit. The internal memory may be directly connected to the memory controller through the memory bus. The external memory connection unit may connect an external memory directly to the memory controller through a portion of signal lines in the memory bus, and may generate a flag signal indicating whether the external memory is connected to the external memory connection unit.
