Seagate Assigned Two Patents on SSD

SSD Assembly

Seagate Technology LLC, Scotts Valley, CA, has been assigned a patent (8,199,506) developed by Peter R. Janik, Shakopee, MN, Darren E. Johnston, Burnsville, MN, and Gordon A. Harwood, Prior Lake, MN, for a "solid state data storage assembly."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A solid state data storage assembly includes thermal interface material that conducts heat away from electrical components of the assembly. In some examples, the thermal interface material is positioned between a printed circuit board assembly, which includes electrical components, and a cover of a housing of the data storage assembly. The thermal interface material may also provide shock protection for the data storage assembly by at least one of increasing a stiffness of the data storage assembly, absorbing some mechanical loads applied to the data storage assembly or distributing the applied loads. In addition, in some examples, the thermal interface material exhibits some tackiness, such that removal of a thermal interface material from a data storage assembly and subsequent repositioning of the thermal interface material within the data storage assembly may provide a visual indication of tampering."

The patent application was filed on August 17, 2009 (12/542,502).

SSD Defragmentation

Seagate Technology LLC, Cupertino, CA, has been assigned a patent (8,190,811) developed by John Edward Moon, Superior, CO, and Todd Ray Strope, Longmont, CO, for a "defragmentation of solid state memory."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A data storage device includes a solid state data storage medium, a set of related data blocks and a controller. The set of related data blocks are non-contiguously stored on the data storage medium and have an original write sequence. The controller, responsive to a defragmentation request, maps the physical block addresses of the set of related data blocks to contiguous logical block addresses in the original write sequence while maintaining the non-contiguous physical block addresses of the set of related data blocks on the data storage medium."

The patent application was filed on June 9, 2009 (12/480,935).
