Controlling data storage in array of storage devices
GlobalFoundries, Inc., Grand Cayman, Cayman Islands, with applicant:International Business Machines Corporation, Armonk, NY, has been assigned a patent (9,378,093) developed by Cooper, Alastair, Winchester, Great Britain, and Hutchison, Gordon D., Eastleigh, Great Britain, for a “controlling data storage in an array of storage devices.

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Methods, apparatus and computer programs have been provided for mitigating a problem of non-optimal recovery from storage device failures. A method involves determining a required write performance for rebuilding data of a failed device, based at least partly on the potential read performance of storage devices in a data rebuild, and allocating a virtual storage area within available storage, which allocation of virtual storage is based at least partly on the required write performance. Data is rebuilt by writing to the allocated virtual storage area, and data recovery is completed by migrating this rebuilt data to at least one data storage device such as a spare physical storage device within the array.

The patent application was filed on March 25, 2014 (14/224,431).

Magnetic memory device and method of forming thereof
GlobalFoundries Singapore Pte. Ltd., Singapore, Singapore, has been assigned a patent (9,343,662) developed by Tan, Juan Boon, Yi, Wanbing, Shum, Danny Pak-Chum, and Jiang, Yi, Singapore, Singapore, for a “magnetic memory device and method of forming thereof.

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A device and a method of forming a device are presented. A substrate is provided. Front end of line processing is performed to form circuit component on the substrate and back end of line processing is performed to include the uppermost inter level dielectric, (ILD) layer. The uppermost ILD layer includes first and second interconnects. A pad level is formed over the uppermost ILD layer. A storage unit of a memory cell is provided in the pad level. The storage unit is coupled to the first interconnect of the uppermost ILD layer. A cell interconnect and a pad interconnect are formed in the pad level. The cell interconnect is formed on top of and coupled to the storage unit and the pad interconnect is coupled to the second interconnect in the uppermost ILD layer.

The patent application was filed on September 11, 2014 (14/483,171).

Memory cell with decoupled channels
GlobalFoundries Singapore Pte. Ltd., Singapore, Singapore, has been assigned a patent (9,343,472) developed by Tan, Shyue Seng, Toh, Eng Huat, Quek, Elgin, and Tang, Yanzhe, Singapore, Singapore, for a “memory cell with decoupled channels.

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A device having a substrate prepared with a memory cell region having a memory cell is disclosed. The memory cell includes an access transistor and a storage transistor. The access transistor includes first and second source/drain, (S/D) regions and the storage transistor includes first and second storage S/D regions. The access and storage transistors are coupled in series and the second S/D regions being a common S/D region. An erase gate is disposed over the common S/D region. A program gate is disposed over the first storage S/D region. Such an arrangement of the memory cell decouples a program channel and an erase channel.

The patent application was filed on December 17, 2014 (14/574,270).

Allocating resource of storage device to storage optimization operation
GlobalFoundries, Inc., Grand Cayman, Cayman Islands, with applicant:International Business Machines Corporation, Armonk, NY, has been assigned a patent (9,342,245) developed by Hu, Xiaoyu, Horgen, Switzerland, Ioannou, Nikolas, Koltsidas, Ioannis, Zurich, Switzerland, Liu, Yang, Mei, Mei, Shanghai, China, Muench, Paul H., San Jose, CA, Pletka, Roman A., Uster, Switzerland, and Wang, ZhiQiang, Shanghai, China, for a “method and system for allocating a resource of a storage device to a storage optimization operation.

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Allocating a resource of a storage device to a storage optimization operation. An available resource of the storage device is monitored. Determining an allocation proportion of the resource allocated to the storage optimization operation, based on at least one of historical running information and a predicted value of a performance improvement caused by the storage optimization operation. Allocating the resource of the storage device to the storage optimization operation based on the available resource and the allocation proportion.

The patent application was filed on August 29, 2014 (14/472,426).

Controlling redundancy parity encoding amount
based on deduplication indications of activity
GlobalFoundries, Inc., Grand Cayman, Cayman Islands, with applicant:GlobalFoundries U.S. 2 LLC, Hopewell Junction, NY, has been assigned a patent (9,336,076) developed by Baldwin, Duane M., Mantorville, MN, Olson, John T., Tucson, AZ, Patil, Sandeep R., and Shiraguppi, Riyazahamad M., Pune, India, for a “system and method for controlling a redundancy parity encoding amount based on deduplication indications of activity.

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”According to one embodiment, a method includes determining, using a processor, which physical blocks are priority physical blocks based on at least one of: a number of application blocks referencing the physical block, and a number of accesses to the physical block, creating a reference to each priority physical block, and outputting the reference. According to another embodiment, a method includes receiving a reference to one or more priority physical blocks in a storage pool, and adjusting an amount of redundancy parity encoding for each of the one or more priority physical blocks based on the reference.

The patent application was filed on August 23, 2013 (13/975,075).

Mapping source workload pattern for source storage system
to target workload pattern for target storage system
GlobalFoundries, Inc., Grand Cayman, Cayman Islands, with applicant:GlobalFoundries U.S. 2 LLC, Hopewell Junction, NY, has been assigned a patent (9,317,215) developed by Chen, Chiahong, Oro Valley, AZ, Chiu, Lawrence Y., Saratoga, CA, Clayton, Nicolas M., Warrington, Great Britain, Fan, Shan, and Liu, Yang, Shanghai, China, for a “mapping a source workload pattern for a source storage system to a target workload pattern for a target storage system.

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Provided are a method, system, and computer program product for mapping a source workload pattern for a source storage system to a target workload pattern for a target storage system. A source workload pattern is received from the source storage system having workload access characteristics of source logical addresses at the source storage system. The source workload pattern at the source logical addresses is mapped to a target workload pattern for target logical addresses at the target storage system. The target workload pattern for the target workload addresses is provided to the target storage system to use to determine storage locations in the target storage system to store received replicated data from the source logical addresses at the target logical addresses.

The patent application was filed on May 23, 2013 (13/901,495).
