SiliconSystems (WD) Assigned Patent

SiliconSystems, Inc., Aliso Viejo, CA, acquired in 2009 by Western Digital Corp., has been assigned a patent (8,166,245) developed by Mark S. Diggs, Laguna Hills, CA, and David E. Merry Jr., Irvine, CA, for a "multi-interface and multi-bus structured solid-state storage subsystem."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A solid-state storage subsystem, such as a non-volatile memory card or drive, includes multiple interfaces and a memory area storing information used by a data arbiter to prioritize data commands received through the interfaces. As one example, the information may store a priority ranking of multiple host systems that are connected to the solid-state storage subsystem, such that the data arbiter may process concurrently received data transfer commands serially according to their priority ranking. A host software component may be configured to store and modify the priority control information in solid-state storage subsystem’s memory area."

The patent application was filed on March 16, 2010 (12/725,139).
