    • A memory apparatus and a method of evenly using the blocks of a flash memory are provided. The memory apparatus comprises a flash memory and a controller. The flash memory comprises a data region with a plurality of data blocks and a spare region with a plurality of spare blocks. The controller is configured to receive data corresponding to the first data block, select a spare block, program data into the spare block when the erase count corresponding to the spare block is less than the predetermined value or to select a second data block and program data stored in the second data block into the spare block when the erased count corresponding to the spare block reaches the predetermined value. As a result, the blocks of the flash memory are used evenly.
    • 提供了一种均匀地使用闪速存储器块的存储装置和方法。 存储装置包括闪速存储器和控制器。 闪速存储器包括具有多个数据块的数据区域和具有多个备用块的备用区域。 控制器被配置为当与备用块相对应的擦除计数小于预定值时,接收对应于第一数据块的数据,选择备用块,将程序数据写入备用块中,或者选择第二数据块和程序数据 当与备用块相对应的擦除计数达到预定值时,将第二数据块中存储在备用块中。 结果,闪存的块被均匀地使用。

    • An optical diffusion device applied in a backlight module includes a plate. Multiple light sources are disposed on one side of the plate. Multiple optical microstructures provided with a longer axis and a shorter axis are disposed on the plate. The longer axis of each optical microstructure is approximately arranged in parallel with a direction extending from the light source, or, in other words, the shorter axis is arranged approximately crossing the direction extending from the light source. A diffusion effect is provided to each light source through the shorter axis of the optical microstructure to increase optical radiant energy among the light sources and to eliminate the dim and dark regions among the light sources for increasing general luminance of the backlight module.
    • 应用在背光模块中的光扩散装置包括板。 多个光源设置在板的一侧。 设置有长轴和短轴的多个光学微结构设置在板上。 每个光学微结构的长轴近似地与从光源延伸的方向平行地布置,或者换句话说,短轴被布置成大致与从光源延伸的方向交叉。 通过光学微结构的较短轴向每个光源提供扩散效果,以增加光源之间的光辐射能量,并消除光源之间的暗淡和暗区域以增加背光模块的一般亮度。

    • The invention comprises a memory module capable of wear-leveling. In one embodiment, the memory module comprises a flash memory and a controller. The flash memory comprises a plurality of management units, wherein each of the management units comprises a plurality of blocks. The controller receives new data with a logical address managed by a first management unit selected from the management units, pops a first spare block from a spare area of the first management unit, determines whether an erase count of the first spare block is greater than a first threshold value, searches a second management unit selected from the management units for a replacing block with an erase count lower than a second threshold value when the erase count of the first spare block is greater than the first threshold value, and directs the first management unit and the second management unit to exchange the first spare block with the replacing block.
    • 本发明包括能够磨损平整的存储器模块。 在一个实施例中,存储器模块包括闪速存储器和控制器。 闪速存储器包括多个管理单元,其中每个管理单元包括多个块。 控制器接收具有由从管理单元选择的第一管理单元管理的逻辑地址的新数据,从第一管理单元的备用区弹出第一备用块,确定第一备用块的擦除次数是否大于 当所述第一备用块的擦除次数大于所述第一阈值时,搜索从所述管理单元中选择的替换块的擦除次数小于第二阈值的第二管理单元,并且指示所述第一管理 单元和第二管理单元与替换块交换第一备用块。
