  • Publication number: 20090254729
    Abstract: According to the method of wear leveling for a non-volatile memory of the present invention, the non-volatile memory is divided into a plurality of windows, and a mapping table is built in which the logical block addresses having frequently accessed data are allocated equally to the plurality of windows. The logical block addresses may store a File Allocation Table (FAT) or a directory table; therefore the windows they locate will be written or erased more frequently. In an embodiment, the logical block addresses having frequently accessed data are allocated on a one-to-one basis to the plurality of windows. For example, the plurality of windows may comprise Windows 0, 1, 2 and 3, the logical block addresses comprise logical block addresses 0, 1, 2 and 3, and logical block addresses 0, 1, 2 and 3 point to Windows 0, 1, 2 and 3, respectively.

  • Publication number: 20080295746
    Abstract: A linear table with an adjustable dust-proof structure is locked with a loading rack on each end of a stator by screw, and each end of an elongated sheet-like dust-proof structure is located on each of the two loading racks. As compared to the conventional plate-like dust-proof structure, the weight of the dust-proof structure of the present invention is widely reduced, thus avoiding the problem of structure bending downwards. Moreover, adjusting the distance between the two loading racks can adjust the strain of the dust-proof structure, further preventing the dust-proof structure from bending downwards.
