  • Publication number: 20090103345
    Abstract: Various embodiments of the present invention are directed to stacked memory modules. In one embodiment of the present invention, a memory module comprises at least one memory-controller layer stacked with at least one memory layer. Fine pitched through vias (e.g., through silicon vias) extend approximately perpendicular to a surface of the at least one memory controller through the stack providing electronic communication between the at least one memory controller and the at least one memory layers. Additionally, the memory-controller layer includes at least one external interface configured to transmit data to and from the memory module. Furthermore, the memory module can include an optical layer. The optical layer can be included in the stack and has a bus waveguide to transmit data to and from the at least one memory controller. The external interface can be an optical external interface which interfaces with the optical layer.

  • Publication number: 20080140994
    Abstract: A method of operation within an integrated-circuit processing device having a plurality of execution lanes. Upon receiving an instruction to exchange data between the execution lanes, respective requests from the execution lanes are examined to determine a set of the execution lanes that may send data to one or more others of the execution lanes during a first interval. Each execution lane within the set of the execution lanes is signaled to indicate that the execution lane may send data to the one or others of the execution lanes.

  • Publication number: 20070152241
    Abstract: A gate capacitor having a horizontal structure and a method for manufacturing the same is provided. The gate capacitor having a horizontal structure can be formed on a semiconductor substrate and used as a MOS transistor. The gate capacitor includes at least two adjacent gate electrodes and a capacitor dielectric layer filled between the two gate electrodes. In this case, insulating spacers can be formed at a sidewall of the gate electrodes in which the capacitor dielectric layer is not formed. As the gate capacitors can be used as a MOS transistor, a gate insulating layer can be formed between the two gate electrodes and the semiconductor substrate.

  • Publication number: 20070152244
    Abstract: Disclosed is a semiconductor transistor for enhancing performance of PMOS and NMOS transistors, particularly current driving performance, while reducing a narrow width effect. A narrow width MOS transistor includes: a channel of which width is W0 and length is L0; an active area including source and drain areas formed at both sides with the channel as a center; a gate insulating layer formed on the channel; a gate conductor formed on the gate insulating layer and intersecting the active area; a first additional active area of width is larger than that W0 of the channel as an active area added to the source area; and a second additional active area of width is larger than that W0 of the channel as an active area added to the drain area. When the structure of the transistor having the additional active areas is applied to NMOS and PMOS transistors, a driving current is represented as 107.27% and 103.31%, respectively. Accordingly, the driving currents of both PMOS and NMOS transistors are enhanced.
