  • Patent number: 7923310
    Abstract: A fabrication method is provided for a core-shell-shell (CSS) nanowire transistor (NWT). The method provides a cylindrical CSS nanostructure with a semiconductor core, an insulator shell, and a conductive shell. The CSS nanostructure has a lower hemicylinder overlying a substrate surface. A first insulating film is conformally deposited overlying the CSS nanostructure and anisotropically plasma etched. Insulating reentrant stringers are formed adjacent the nanostructure lower hemicylinder. A conductive film is conformally deposited and selected regions are anisotropically plasma etched, forming conductive film gate straps overlying a gate electrode in a center section of the CSS nanostructure. An isotropically etching removes the insulating reentrant stringers adjacent the center section of the CSS nanostructure, and an isotropically etching of the conductive shell overlying the S/D regions is performed. A screen oxide layer is deposited over the CSS nanostructure.

  • Patent number: 7912078
    Abstract: A system and method are provided for controlling information flow from a channel service module (CSM) in an asymmetric channel environment. The method provides information for transmission to an OSI model PITY (physical) layer device with a channel buffer. The PHY device channel buffer current capacity is estimated. Information is sent to the channel buffer responsive to estimating the channel buffer capacity, prior to receiving a Polling Result message from the PHY device. Initially, Polling Request messages are sent to the PHY device, and Polling Result messages received from the PHY device, as is conventional. In response to analyzing the Polling messages, a transmission pattern is determined, which includes the amount of information to transmit and a period between transmissions.

  • Patent number: 7904705
    Abstract: A system and method are provided for updating a speculative global history prediction record in a microprocessor system using pipelined instruction processing. The method accepts microprocessor instructions with consecutive operations, including a conditional branch operation with an associated first branch address. A speculative global history record (SGHR) of conditional branch resolutions and predictions is accessed and hashed with the first branch address, creating a first hash result. The first hash result is used to index a branch history table (BHT) of previous first branch resolutions. As a result, a first branch prediction is made, and the SGHR is updated with the first branch prediction. A non-speculative global history record (NSGHR) of branch resolutions is updated with the resolution of the first branch operation, and if the first branch prediction is incorrect, the SGHR is corrected using the NSGHR.

  • Patent number: 7887980
    Abstract: A sub-resolutional grayscale reticle and associated fabrication method have been presented. The method provides a transparent substrate, and forms a plurality of coincident partial-light transmissive layers overlying the transparent substrate. A pattern is formed, sub-resolutional at a first wavelength, in at least one of the transmissive layers. If there are n transmissive layers, the reticle transmits at least (n+1) intensities of light. In one aspect, each of the plurality of transmissive layers has the same extinction coefficient and the same thickness. In other aspects, the transmissive layers may have different thickness. Then, even if the extinction coefficients are the same, the attenuation of light through each layer is different. The transmission characteristics of the reticle can be further varied if the transmissive layers have different extinction coefficients. Likewise, the transmission characteristics through the sub-resolutional patterns can be varied.

  • Patent number: 7872309
    Abstract: A recessed-gate thin-film transistor (RG-TFT) with a self-aligned lightly doped drain (LDD) is provided, along with a corresponding fabrication method. The method deposits an insulator overlying a substrate and etches a trench in the insulator. The trench has a bottom and sidewalls. An active silicon (Si) layer is formed overlying the insulator and trench, with a gate oxide layer over the active Si layer. A recessed gate electrode is then formed in the trench. The TFT is doped and LDD regions are formed in the active Si layer overlying the trench sidewalls. The LDD regions have a length that extends from a top of the trench sidewall, to the trench bottom, with a doping density that decreases in response to the LDD length. Alternately stated, the LDD length is directly related to the depth of the trench.

  • Patent number: 7869468
    Abstract: A system and method are provided for transporting a serial stream via a lower speed network using multiple parallel paths. At a transmitter, an optical or electromagnetic waveform is accepted representing a serial stream of digital information, and unbundled into n virtual information streams. Each virtual information stream is divided into a sequence of segments. Each segment is encapsulated, creating a sequence of packets by adding a start indicator to the beginning of each segment, and a terminate indicator to the end of each segment. Each packet is disinterleaved across m lanes and reinterleaved into n branches of framed data. Optical or electromagnetic waveforms representing the framed data are transmitted via n network branches. A receiver is also provided, which essentially reverses the above-described transmission method.

  • Patent number: 7849299
    Abstract: Provided is a means for accessing multiple entries from a branch history table (BHT) in a single clock cycle, in the context of pipelined instruction processing. In a first clock cycle, a plurality of conditional branch instructions is fetched. A value is accessed from a global history record (GHR) of conditional branch resolutions and predictions for a fetched conditional branch instruction. An associated instruction address is hashed with a left-shifted GHR value. The result is used to access a word in an indexed BHT stored in a single-port random access memory (RAM). The word comprises a branch direction count for the plurality of fetched conditional branch instructions. In a second clock cycle a conditional branch instruction is executed at an execute stage and the BHT is written with an updated branch direction count in response to a resolution of the executed conditional branch instruction.

  • Patent number: 7849209
    Abstract: A system and method are provided for negotiating a link data rate in a communication system using a plurality of data rates. In a system including a first device network-connected to a second device, auto-negotiation (AN) messages are mutually transmitted. The AN messages indicate rate information such as preferred data rate capabilities, if the device has a dual-rate capability, or a single data rate capabilities. If the AN messages are mutually transmitted, a negotiated link data rate is established. However, if one of the devices cannot send AN messages, the other device times-out, and a link data rate is established at the data rate transmitted by the device that is not AN-capable.

The method accepts a microprocessor instruction of consecutive operations, including a conditional branch operation with an associated branch address, at a first stage in a pipelined microprocessor execution process. A global history record (GHR) of conditional branch resolutions and predictions is accessed and hashed with the branch address, creating a first hash result. The first hash result is used to access an indexed branch history table (BHT) of branch direction counts and the BHT is used to make a branch prediction. If the branch prediction being “taken”, the current GHR value is left-shifted and hashed with the branch address, creating a second hash result which is used in creating an updated GHR.
