Patent Issued for Data Stripes and Addressing for Flash Memory Devices

May 27, 2014



By a News Reporter-Staff News Editor at Journal of Technology -- Seagate Technology LLC (Cupertino, CA) has been issued patent number 8724401, according to news reporting originating out of Alexandria, Virginia, by VerticalNews editors.

The patent's inventors are Friendshuh, Luke William (Elko, MN); Gaertner, Mark Allen (Vadnais Heights, MN); Haines, Jonathan Williams (Boulder, CO); Feldman, Timothy Richard (Louisville, CO).

This patent was filed on September 29, 2009 and was published online on May 13, 2014.

From the background information supplied by the inventors, news correspondents obtained the following quote: "Flash memory devices store data to and retrieve data from transistors. Commonly, the transistors are grouped into pages, pages are grouped into erasure blocks, and erasure blocks are grouped into programmable devices. Data is written to flash devices at the page level, and data is erased from flash devices at the block level. Before writing to a particular page, all of the pages in the block are erased.

"One issue with flash memory devices has been limited life times. The flash transistors are only able to be programmed and erased a finite amount of times. Another issue has been writing performance. Although data is generally read from flash devices relatively quickly, writing data to and erasing data from flash devices can be time consuming."

Supplementing the background information on this patent, VerticalNews reporters also obtained the inventors' summary information for this patent: "An aspect of the disclosure relates to data stripes and addressing for flash memory devices. Flash memory devices illustratively have a plurality of programmable devices that are capable of simultaneously storing data. A plurality of erasure blocks are within each of the programmable devices, and each erasure block has pages of transistors. The flash memory devices are logically organized as a plurality of stripes. Each stripe has a height and a width. In an embodiment, the stripe height is greater than one page. In another embodiment, the stripe width is less than all of the programmable devices within the flash memory device.

"These and various other features and advantages that characterize the claimed embodiments will become apparent upon reading the following detailed description and upon reviewing the associated drawings."
