    摘要: Non-volatile solid state mass storage device and methods for improving write performance thereof. The storage device includes a NAND flash controller, an array of NAND flash memory integrated circuits, and means for determining a lowest unused page number of each write target block in a group of the NAND flash memory integrated circuits that are simultaneously accessible at any given time by a write command. The storage device has further means for programming a dummy write to at least a first write target block in a first NAND flash memory integrated circuit within the group of NAND flash memory integrated circuits if the lowest unused page number within the first write target block is lower than the lowest unused page number of a second write target block in a second NAND flash memory integrated circuit in the group of NAND flash memory integrated circuits.

    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 for minimizing the degradation of performance upon accessing a flash memory using a logical-physical mapping scheme, and a method for efficiently storing and managing information on logical-physical mapping in a flash memory. A method for writing data in a flash memory includes determining whether a sector is empty in a physical page having a most recently written logical page number of data to be written, the offset of the sector matching that of the data to be written; if the sector is empty, writing the data in the sector to the physical page; and if the sector is not empty, selecting an empty physical page to write the data to a sector in the selected empty physical page of which the offset matches that of the data to be written and writing a logical page number for the data to the selected empty physical page.

    摘要: An apparatus for reducing a page fault rate in a virtual memory system includes a page table stored in a main storage unit which stores a reference address so as to read page information from the main storage unit; a buffer unit which stores a portion of the page table; and a processor which reads data from the main storage unit or which stores data in the main storage unit. When changing information for referring to a first page that exists in the page table, the processor performs a task invalidating information related to the first page in the buffer unit. A method of reducing the page fault rate includes resetting reference information stored in the page table; detecting whether the reference information exists in a buffer unit; and invalidating the reference information when the reference information exists in the buffer unit.
