摘要： An operation method of a memory includes the steps of calculating an offset of sequential write commands and the beginning of pages of a block of a non-volatile memory; shifting the block by the offset; and directly writing data from a host to the pages except the first and last pages of the block by the sequential write commands. In an embodiment, the pages are logical pages providing optimal writing efficiency and are determined before calculating the offset. The step of shifting the block by the offset is to increase corresponding logical block addresses (LBA) in the pages by the offset.

摘要： A method of wear leveling for a non-volatile memory is disclosed. A non-volatile memory is divided into windows and gaps, with each gap between two adjacent windows. The windows comprise physical blocks mapped to logical addresses, and the gaps comprise physical blocks not mapped to logical addresses. The windows are shifted through the non-volatile memory in which the mapping to the physical blocks in the window to be shifted is changed to the physical blocks in the gap.

摘要： A method of wear leveling for a non-volatile memory is performed as follows. First, the non-volatile memory is divided into a plurality of zones including at least a first zone and a second zone. The first zone is written and/or erased in which one or more logical blocks have higher writing hit rate, and therefore the corresponding physical blocks in the first zone will be written more often. The next step is to find one or more free physical blocks in second zone. The physical blocks of the first zone are replaced by the physical blocks of the second zone if the number of write and/or erase to the first zone exceeds a threshold number. The replacement of physical blocks in the first zone by the physical blocks in the second zone may include the steps of copying data from the physical blocks in the first zone to the physical block in the second zone, and changing the pointer of logical blocks to point to the physical blocks in the second zone.
摘要翻译：如下执行用于非易失性存储器的磨损均衡的方法。首先，非易失性存储器被分成包括至少第一区域和第二区域的多个区域。写入和/或擦除第一区域，其中一个或多个逻辑块具有较高的写入命中率，因此第一区域中相应的物理块将被更频繁地写入。下一步是在第二个区域中找到一个或多个空闲的物理块。如果第一区的写入次数和/或擦除次数超过阈值，则第一区的物理块被第二区的物理块替换。通过第二区域中的物理块来替换第一区域中的物理块可以包括以下步骤：将数据从第一区域中的物理块复制到第二区域中的物理块，并将逻辑块的指针改变为点到第二区的物理块。

摘要： A method is employed to manage a memory, e.g., a flash memory, including a plurality of paired pages. Each paired page includes a page and a respective risk zone. For each write command, at least one unwritten page is selected for writing new data. For each unwritten page whose risk zone includes at least one written page, each written page is copied or backed up, and the new data is written to the unwritten page. For each unwritten page whose risk zone lacks a written page, the new data is written to the unwritten page. In an embodiment, the written page is copied only if the unwritten page and the written page are operated by different write commands.

摘要： 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.
摘要翻译：根据本发明的非易失性存储器的磨损均衡方法，将非易失性存储器划分为多个窗口，并且构建了具有频繁访问的数据的逻辑块地址被均等地分配的映射表到多个窗口。逻辑块地址可以存储文件分配表（FAT）或目录表; 因此，他们找到的窗口将被更频繁地写入或擦除。在一个实施例中，具有频繁访问的数据的逻辑块地址被分配给多个窗口。例如，多个窗口可以包括Windows 0,1,2和3，逻辑块地址包括逻辑块地址0,1,2和3，逻辑块地址0,1,2和3指向Windows 0，分别为1,2和3。
