摘要： A method of writing data to a range of logical blocks in a storage medium includes: receiving a command including a starting logical block address, a value indicating a range of logical block addresses to be written, and a logical block of data; storing the logical block in a first temporary storage; generating a logical page by duplicating the logical block a plurality of times corresponding to a number of logical blocks in a logical page and transporting the generated logical page to a second temporary storage and storing the generated logical page in the second temporary storage; writing the generated logical page from the second temporary storage into the storage medium beginning from the starting logical block address; and performing a read-modify-write operation if the first write operation does not begin on a logical page boundary or the last write operation does not end on a logical page boundary.
摘要翻译：一种将数据写入存储介质中的一系列逻辑块的方法包括：接收包括开始逻辑块地址，指示要写入的逻辑块地址范围的值以及逻辑数据块的命令; 将逻辑块存储在第一临时存储器中; 通过与逻辑页面中的多个逻辑块对应多次复制逻辑块并将所生成的逻辑页面传输到第二临时存储器并将生成的逻辑页面存储在第二临时存储器中来生成逻辑页面; 将所生成的逻辑页面从所述第二临时存储器写入所述存储介质中，从所述开始逻辑块地址开始; 以及如果第一写入操作没有在逻辑页面边界上开始或者最后的写入操作没有在逻辑页面边界上结束，则执行读取 - 修改 - 写入操作。

摘要： A data storage device comprises a plurality of non-volatile memory devices storing physical pages, each stored at a predetermined physical location. A controller may be coupled to the memory devices and configured to access data stored in a plurality of logical pages (L-Pages), each associated with an L-Page number that enables the controller to logically reference data stored in the physical pages. A volatile memory may comprise a logical-to-physical address translation map that enables the controller to determine a physical location, within the physical pages, of data stored in each L-Page. The controller may be configured to maintain, in the memory devices, journals defining physical-to-logical correspondences, each journal covering a predetermined range of physical pages and comprising a plurality of entries that associate one or more physical pages to each L-Page. The controller may read the journals upon startup and rebuild the address translation map from the read journals.

摘要： A method of performing an atomic write command in a data storage device comprising a volatile memory and a plurality of non-volatile memory devices configured to store a plurality of physical pages. The method may comprise storing data in a plurality of logical pages (L-Pages), each associated with a logical address. A logical-to-physical address translation map may be maintained in the volatile memory, and may be configured to enable determination of a physical location, within one or more of the physical pages, of the data referenced by each logical address. The data specified by a received atomic write command may be stored one or more L-Pages. Updates to the entry or entries in the translation map associated with the L-Page(s) storing the data specified by the atomic write command may be deferred until all L-Pages storing data specified by the atomic write command have been written in a power-safe manner.

摘要： A data storage device may comprise a plurality of Multi-Level Cell (MLC) non-volatile memory devices comprising a plurality of lower pages and a corresponding plurality of higher-order pages. A controller may be configured to write data to and read data from the plurality of lower pages and the corresponding plurality of higher-order pages. A buffer may be coupled to the controller, which may be configured to accumulate data to be written to the MLC non-volatile memory devices, allocate space in the buffer and write the accumulated data to the allocated space. At least a portion of the accumulated data may be written in a lower page of the MLC non-volatile memory devices and the space in the buffer that stores data written to the lower page may be de-allocated when all higher-order pages corresponding to the lower page have been written in the MLC non-volatile memory devices.
