Patent number: 8736353Abstract: System and method system for regulating voltage in a portion of an integrated circuit. An integrated circuit has a voltage input and at least a portion that is less than all of the integrated circuit, which requires a local voltage level. A voltage selector establishes a target voltage for the portion. A first comparator compares the target voltage to the local voltage and generates a pull up control signal when the local voltage is below the target voltage. A second comparator compares the target voltage to the local voltage and generates a pull down control signal when the local voltage is above the target voltage. A pull up device, responsive to the pull up control signal, increases the local voltage according to the pull up control signal. A pull down device, responsive to the pull down control signal, decreases the local voltage level according to the pull down control signal.Type: GrantFiled: September 18, 2012Date of Patent: May 27, 2014Assignee: International Business Machines CorporationInventor: Kerry Bernstein

Patent number: 8729549Abstract: A plurality of peripheral test structure substrate (PTSS) through vias is formed within a peripheral test structure substrate. A peripheral test structure layer and at least one functional layer are formed on one side of the plurality of the PTSS through vias. The other side of the plurality of the PTSS through vias is exposed throughout fabrication of the peripheral test structure layer and the at least one functional layer to provide access points for testing functionality of the various layers throughout the manufacturing sequence. C4 bonding may be performed after manufacture of all of the at least one functional layer is completed. A 3D assembly carrier or a C4 carrier substrate is not required since the peripheral test structure substrate has sufficient mechanical strength to support the peripheral test structure layer and the at least one functional layer.Type: GrantFiled: June 26, 2012Date of Patent: May 20, 2014Assignee: International Business Machines CorporationInventors: Kerry Bernstein, Jerome L.

Patent number: 8686559Abstract: A stacked semiconductor chip comprising multiple unit chips contains multiple instances of a first chip component that have a low yield and are distributed among the multiple unit chips. An instance of the first chip component within a first unit chip is logically paired with at least another instance of the first chip component within at least another unit chip so that the combination of the multiple instances of the first chip component across the multiple unit chips constitute a functional block providing the functionality of a fully functional instance of the first chip component. The stacked semiconductor chip may include multiple instances of a second chip component having a high yield and distributed across the multiple unit chips. Multiple low yield components constitute a functional block providing an enhanced overall yield, while high yield components are utilized to their full potential functionality.Type: GrantFiled: September 8, 2012Date of Patent: April 1, 2014Assignee: International Business Machines CorporationInventors: Kerry Bernstein, Philip G.

Patent number: 8575964Abstract: Localized logic regions of a circuit include a local comparator electrically connected to a local resistive voltage circuit, to a local resistive ground circuit, and to a local register structure. The local comparator supplies a clock pulse to the local register structures when the local reference voltage is below a local voltage threshold. Activity in the local combinatorial logic structure causes the local reference voltage to drop below the local reference voltage independently of changes in the global reference voltage causing the comparator to output the clock pulse (with sufficient delay to allow the logic results to be stored in the registers only after setup times have been met in the local logic devices). This eliminates the need for a clock distribution tree, thereby saving power when there is no activity in the local combinatorial logic structure.Type: GrantFiled: March 22, 2012Date of Patent: November 5, 2013Assignee: International Business Machines CorporationInventors: Kerry Bernstein, Kenneth J.

Patent number: 8576599Abstract: A multi-wafer CAM cell in which the negative effects of increased travel distance have been substantially reduced is provided. The multi-wafer CAM cell is achieved in the present invention by utilizing three-dimensional integration in which multiple active circuit layers are vertically stack and vertically aligned interconnects are employed to connect a device from one of the stacked layers to another device in another stack layer. By vertically stacking multiple active circuit layers with vertically aligned interconnects, each compare port of the inventive CAM cell can be implemented on a separate layer above or below the primary data storage cell. This allows the multi-wafer CAM structure to be implemented within the same area footprint as a standard Random Access Memory (RAM) cell, minimizing data access and match compare delays.Type: GrantFiled: February 2, 2012Date of Patent: November 5, 2013Assignee: International Business Machines CorporationInventors: Jagreet S.
