Patent number: 8631188Abstract: A data storage device is disclosed comprising a non-volatile memory, such as a disk of a disk drive or a non-volatile semiconductor memory. First and second write commands are received from a host, and in response first and second write data are requested from the host. The first write data is stored in the non-volatile memory, and after storing the first write data, a first acknowledge is transmitted to the host to acknowledge completion of the first write command. After transmitting the first acknowledge, a third write command is received from the host. The second write data is stored in the non-volatile memory, and after storing the second write data, a second acknowledge is transmitted to the host acknowledging completion of the second write command. After transmitting the second acknowledge, third write data is requested from the host associated with the third write command.Type: GrantFiled: September 2, 2009Date of Patent: January 14, 2014Assignee: Western Digital Technologies, Inc.Inventors: Mark A.

Patent number: 7325155Abstract: An embedded system with reduced susceptibility to single event upset effects. The system includes an instruction memory that can store at least one instruction set. The instruction memory utilizes a parity checking error-detection scheme. The system also includes a non-volatile memory that can store a copy of the at least one instruction set, and a data memory that can store at least one data sequence. The data memory utilizes an error correction coding (ECC) scheme. A controller, which is responsive to the instruction memory, the non-volatile memory, and the data memory, replaces the at least one instruction set in the instruction memory with the copy of the at least one instruction set from the non-volatile memory, if a parity error is detected in connection with the at least one instruction set in the instruction memory. The controller also operates in conjunction with the data memory to implement the ECC scheme.Type: GrantFiled: September 14, 2004Date of Patent: January 29, 2008Assignee: Seagate Technology LLCInventors: Jon D.

Patent number: 7003644Abstract: A disc drive with a control processor programmed with an execution time dependent command schedule optimization method to effect data throughput with a host device. The disc drive includes a head disc assembly executing commands scheduled by the control processor. The control processor selects and schedules a next optimum command from among commands analyzed by the control processor during a time the head disc assembly is executing a current command. The steps utilized by the control processor to select and schedule the next optimum command include executing a first command with the head disc assembly, determining a computation time for a second command, storing the computation time as a computation time estimate, and using the stored computation time estimate to determine the number of commands in a command queue for analysis to provide a level of command schedule optimization commensurate with the available time.Type: GrantFiled: October 25, 2002Date of Patent: February 21, 2006Assignee: Seagate Technology LLCInventors: Mark A.

Publication number: 20060016146Abstract: A method of fabricating a structural panel utilizing commercially available trusses comprising aligning a plurality of selected fillers with a plurality of selected trusses in an alternating sequence. The aligned trusses and fillers are pressed to form a panel core. Commercially available wire mesh is overlayed over opposing side surfaces of the panel core and the wire mesh is attached to the trusses by attaching commercially available metal ties to connection points of the wire mesh and trusses to hold the panel core together. The alignment of the fillers and trusses can be adjusted to accommodate different size fillers and/or trusses. Likewise, the positions of the fillers and/or trusses can be adjusted.Type: ApplicationFiled: April 12, 2004Publication date: January 26, 2006Inventor: Mark Heath
