    摘要： In one embodiment, the method includes determining in which of a plurality of memory portions to store a received file based on received characterizing information characterizing content of the file. For example, at least two of the plurality of memory portions are in a same memory. As another example, at least two of the plurality of memory portions are in different memories. The received characterizing information may include at least one of a name of the file, a file name extension of the file, a type of the file, and symbolic information representing the file.

    摘要： In one aspect, a determination is made as whether partition metadata of a solid state memory has changed, and if so, the partition metadata is analyzed to locate invalid data stored in the solid state memory. This analysis may include determining that a file system type of a partition has changed, and invalidating data in response to the changed file system type. Alternately, or in addition, the analysis may include determining that a partition has changed, and invalidating data in response to the changed partition.

    摘要： A device driver including a flash memory file system and method thereof and a flash memory device and method thereof are provided. The example device driver may include a flash memory file system configured to receive data scheduled to be written into the flash memory device, the flash memory file system selecting one of a first data storage area and a second data storage area within the flash memory device to write the received data to based upon an expected frequency of updating for the received data, the first data storage area configured to store data which is expected to be updated more often than the second data storage area. The example flash memory device may include a first data storage area configured to store first data, the first data having a first expected frequency for updating and a second data storage area configured to store second data, the second data having a second expected frequency of updating, the first expected frequency being higher than the second expected frequency.

    摘要： A data storage device for processing a command includes a host interface and a controller. The host interface stores program information sent within the command from a host. The controller decodes the program information that indicates a memory type to be accessed for the command. In addition, the controller determines whether the specified memory type can be accessed according to the command. The controller performs the command by accessing the memory type when the memory type specified by the program information is available for access.

    摘要： A storage system includes a storage medium configured to store data and a buffer memory configured to buffer data to be written to the storage medium. The storage system further includes a controller configured to selectively transfer the buffered data to the storage medium responsive to an invalidity indicator received from an external source. For example, the invalidity indicator may comprise unwrite information received from an external source, e.g., information that indicates that selected buffered data corresponds to deleted file data.
