摘要： A method of re-mapping a flash memory, which minimizes the number of times the flash memory, is accessed and helps to evenly use the entire area of the flash memory, is provided. The method includes arranging a plurality of physical units yet to be mapped according to their erase count values, and sequentially mapping the physical units to a logic unit in such a manner that a physical unit having a smaller erase count value is mapped to the logic unit ahead of a physical unit having a larger erase count value.

摘要： A data management device and a data management method for a flash memory, in which physical addresses are classified according to pages, each of which is a physical data operation unit, and a predetermined data operation is performed with respect to the classified physical addresses. The data management device and method reduce time required for the data operation in a large-block flash memory, in which a physical data operation unit is larger than a logical data operation unit. As a result, an optimal data operation can be achieved in a large-block flash memory.

摘要： A demand paging apparatus and a method for an embedded system are provided. The demand paging apparatus includes a nonvolatile storage device, a physical memory, a demand paging window, and a demand paging manager. The nonvolatile storage device stores code and data which are handled by demand paging. The physical memory processes information about a requested page that is read from the nonvolatile storage device. The demand paging window generates a fault for the page and, thus, causes demand paging to occur. The demand paging window is part of an address space to which an application program stored in the nonvolatile storage device refers. The demand paging manager processes the page fault generated in the demand paging window.

摘要： A method and apparatus for reducing a page replacement time in a system using a demand paging technique are provided. The apparatus includes a memory management unit which transmits a signal indicating that a page fault occurs, a device driver which reads a page having the page fault from a nonvolatile memory, and a page fault handler that searches and secures a space for storing the page having the page fault in a memory. The searching and securing of the space in the memory is performed within a limited time calculated beforehand and a part of data to be loaded to the memory of the system is stored in the nonvolatile memory.
