From the background information supplied by the inventors, news correspondents obtained the following quote: "The present invention generally relates to flash storage devices, and more particularly to systems and methods of storing data in a flash storage device.
"Flash storage devices are increasing used for storing data in electronic applications. In many such applications, the flash storage device stores data in a storage block of a flash storage by partitioning data among sectors having the same fixed size and writing the sectors to the storage block. To maximize data storage capacity of the flash storage device, the flash storage is selected so that the block size of the flash storage is an integer multiple of the fixed sector size of the flash storage device.
"In some applications, data for a particular software program is organized in a data size that is less than the fixed sector size of the flash storage device. In these applications, one or more bits of each sector are not used to store useful data. For example, higher order bits of each sector may be set to a value of zero. Consequently, the data storage capacity of the flash storage device is reduced for the particular application.
"In light of the above, a need exists for a flash storage device that efficiently stores data of different data sizes."
Supplementing the background information on this patent, VerticalNews reporters also obtained the inventors' summary information for this patent: "In various embodiments, a flash storage device includes a flash storage for storing data and a controller for selecting a sector size of the data. The controller allocates the data among data sectors having the sector size and writes the data sectors to the flash storage. In this way, the flash storage device efficiently stores the data in the flash storage device. Moreover, the flash storage device is capable of selecting the sector size to maximize the data storage capacity of the flash storage device. In a further embodiment, the controller generates system data and stores the system data in the data sectors or a system sector, or both.
"A flash storage device, in accordance with one embodiment, includes a flash storage and a controller. The controller is configured to receive a command comprising data, select a sector size, and allocate the data among a plurality of sectors comprising a plurality of data sectors each having the sector size. Additionally, the controller is configured to write the data sectors to the flash storage.
"A flash storage device, in accordance with one embodiment, includes a flash storage and a controller. The controller is configured to receive a command comprising data, select a sector size, and allocate the data among a plurality of sectors comprising at least one data sector, each of which has the sector size, and a system sector. Additionally, the controller is configured to write each data sector to the flash storage.
"A method of transferring data in the flash storage device comprising a flash storage, in accordance with one embodiment, includes receiving a command comprising data. The method also includes selecting a sector size, identifying a storage block in the flash storage based on the command, and allocating the data among a plurality of sectors comprising a plurality of data sectors each having the sector size. Further, the method includes writing the data sectors to the storage block."
