Patent number: 11676659Abstract: A method for operating a memory device includes initiating an access operation to a corresponding row of an array of bit cells of the memory device. Responsive to an expansion mode signal having a first state, the method further includes dynamically operating each column of a plurality of columns of the array to access each bit cell of a corresponding row within the plurality of columns during the access operation. Alternatively, responsive to the expansion mode state signal having a second state different than the first state, the method includes dynamically operating each column of a first subset of columns of the plurality of columns to access each bit cell of a corresponding row within the first subset of columns during the access operation, and maintaining each column of a second subset of columns of the plurality of columns in a static state during the access operation.Type: GrantFiled: November 19, 2021Date of Patent: June 13, 2023Assignee: Advanced Micro Devices, Inc.Inventors: John Wuu, Martin Paul Piorkowski

Patent number: 10054167Abstract: A two-stage stiffness driveshaft includes a hollow cylinder having first and second ends and a hollow cylinder stiffness. An inner shaft having first and second ends and an inner shaft stiffness extends through the hollow cylinder. The inner shaft's first end and the hollow cylinder's first end are engaged via a rotational clearance fit. The inner shaft's second end is rotationally fixed to the hollow cylinder's second end to permit the inner shaft's first end to twist through a predetermined angle relative to the inner shaft's second end. The inner shaft's stiffness defines the driveshaft's first-stage stiffness, while the combined stiffness of the inner shaft and the hollow cylinder defines the driveshaft's second-stage stiffness. A damping element positioned between the inner shaft and the hollow cylinder controls variation in torque transmitted by the driveshaft and generates gradual transition between the first-stage stiffness and the second-stage stiffness.Type: GrantFiled: April 22, 2016Date of Patent: August 21, 2018Assignee: GM Global Technology Operations LLCInventors: Paul A. Piorkowski, Michael J. Grimmer, Mark Gehringer, Stephanie A. Erntser, Eric J Defenderfer, Stephen H. Miller

Patent number: 9770947Abstract: An axle-shaft system for transmitting torque in a motor vehicle drive-train includes first and second two-stage stiffness axle-shafts. Each axle-shaft includes a hollow cylinder having first and second ends and a hollow cylinder stiffness. The axle-shaft also includes an inner shaft extending through the hollow cylinder, and having first and second ends and an inner shaft stiffness. The inner shaft's and the hollow cylinder's first ends are engaged via a rotational clearance fit. The inner shaft's and the hollow cylinder's second ends are rotationally fixed to permit the inner shaft's first end to twist relative to the inner shaft's second end. The inner shaft's stiffness defines the axle-shaft's first-stage stiffness, while the inner shaft's and the hollow cylinder's combined stiffness defines the axle-shaft's second-stage stiffness. At least one of the first-stage and second-stage stiffness of the first axle-shaft is dissimilar from the respective stiffness of the second axle-shaft.Type: GrantFiled: April 22, 2016Date of Patent: September 26, 2017Assignee: GM Global Technology Operations LLCInventor: Paul A.

Patent number: 8701851Abstract: A selectable mass flywheel assembly for a powertrain of a motor vehicle includes a first mass and a second mass. The first mass is connected to a crankshaft of an engine and the second mass engages with a clutch to transfer torque from the engine to a transmission. The two masses are rotationally coupled to each other with a spring and damper assembly. The flywheel assembly further includes a locking mechanism that engages both masses during the startup of the engine to lock the two masses together to minimize the vibrations and pulsations in the powertrain during startup of the engine.Type: GrantFiled: May 4, 2011Date of Patent: April 22, 2014Assignee: GM Global Technology Operations LLCInventors: Michael Partridge, Robert A.

Publication number: 20120234131Abstract: A dual-mass flywheel is provided for a vehicle drivetrain having an internal combustion engine and a transmission. The dual-mass flywheel includes a primary mass adapted for connection to the engine and a secondary mass operatively connected to the primary mass and adapted for connection to the transmission. The clutching mechanism is configured to lock the secondary mass to the primary mass up to a threshold speed of the engine to reduce noise, vibration, and harshness (NVH) during start up of the engine. The clutching mechanism is also configured to release the secondary mass from the primary mass above the threshold speed. A motor vehicle employing the disclosed dual-mass flywheel is also provided.Type: ApplicationFiled: March 16, 2011Publication date: September 20, 2012Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Darrell Lee Robinette, William L.
