Reducing TCP connection establishment time in an overlay network
Applications that run on an overlay network-based managed service achieve high performance gains using a set of TCP optimizations. In a first optimization, a typical single TCP connection between a client and an origin server is broken into preferably three (3) separate TCP connections. These connections are: an edge-to-client connection, an edge-to-edge connection, and edge-to-origin connection. A second optimization replicates TCP state along the connection to increase fault tolerance. In this approach, preferably a given TCP connection is maintained on two servers. When a packet is received by one server, called the primary, its state is updated and then passed to a second server, called the backup. Only when the backup sends an acknowledgement back to the primary can it then send a TCP acknowledgement back to the host that originally sent the packet. Another optimization reduces connection establishment latency. |

Systems and methods for detecting replay attacks on security space
A system and method for detecting replay attacks on secure data are disclosed. A system on a chip (SOC) includes a security processor. Blocks of data corresponding to sensitive information are stored in off-chip memory. The security processor uses an integrity data structure, such as an integrity tree, for the blocks. The intermediate nodes of the integrity tree use nonces which have been generated independent of any value within a corresponding block. By using only the nonces to generate tags in the root at the top layer stored in on-chip memory and the nodes of the intermediate layers stored in off-chip memory, an amount of storage used is reduced for supporting the integrity tree. When the security processor detects events which create access requests for one or more blocks, the security processor uses the integrity tree to verify a replay attack has not occurred and corrupted data. |

Described are techniques for modifying the data rate used to transmit audio data from a master device to slave devices. After receiving a signal, each slave device requests transmission of one or more packets and reports an individual error rate. A cumulative error rate may also be determined based on the individual error rates and the retransmission requests. If any individual error rate or the cumulative error rate exceeds a maximum threshold, the data rate used to transmit the audio data is decreased. If an individual error rate is less than a minimum threshold, the data rate may be increased. If an error rate exceeds a critical threshold, the data rate may be reduced to a minimum value supported by the devices. |

Analog delay based fractionally spaced n-tap feed-forward equalizer for wireline and optical transmitters
An analog-based architecture is used to produce tap spacings in an n-tap fractionally-spaced equalizer without the need for digital clock-driven elements. The analog voltage-controlled delay cell circuits control the amount of applied delay based on the measured phase difference between quarter-rate clock signals. Because low speed clock signals are sufficient for comparison purposes, the analog delay cells can be placed before the quarter-rate multiplexors in the data path. The use of analog-based delay cells eliminates the need to route high-speed clock signals to multiple digital delay elements that are typically used to achieve fractionally spaced data signals in n-tap FIR equalizers. Timing margin issues can also be eliminated since digital clocked elements are not used to produce the fractionally spaced delays. The analog-based delay approach also consumes less power relative equalizers that use multiple digital delay elements requiring high speed clock signals. |

Methods, systems, and devices are described for wireless communication at a device.

Optoelectronic device with resonant suppression of high order optical modes and method of making same
Optical beam quality of an optoelectronic device is improved by suppression of high-order transverse optical modes by their resonant interaction with the continuum of modes in the surrounding regions, such continuum being realized by replacement of one or several layers by layers having a lower refractive index. In particular, selective oxidation of GaAlAs-based vertical cavity surface emitting laser results in (Ga)AlO layers surrounding the aperture and having a lower refractive index than the original (Ga)AlAs layers. The continuum of optical modes originates due to the modification of the optical field in the areas surrounding the aperture caused by the low index insertions positioned to result in enhancement of the optical field in their vicinity. High-order lateral optical modes in the aperture region exhibit larger leakage losses than the fundamental lateral optical mode due to the resonant interaction with the continuum of modes outside the aperture, enabling single-mode lasing from a broad aperture vertical cavity surface emitting laser. |

Integrating standard-gate and extended-gate nanosheet transistors on the same substrate
Embodiments of the invention are directed to fabrication operations for co-integrating standard-gate (SG) and extended-gate (EG) nanosheet/nanowire transistors on the same substrate. The SG and EG nanosheet/nanowire transistors share certain fabrication operations for certain features. For example, the processes to form the bottommost channel nanosheet, the bottommost sacrificial nanosheet, and the topmost channel nanosheet are the same for SG nanosheet transistors and the EG nanosheet transistors. Because the thickness of the sacrificial nanosheet needs to be thicker for EG nanosheet transistors, a thickness of the bottommost sacrificial nanosheet is selected to accommodate the design parameters of the EG nanosheet transistor. Because the thickness of the SG and the EG channel nanosheets do not need to be different, a thickness of the bottommost channel nanosheet and the topmost channel nanosheet can be selected to accommodate the design parameters of both the SG and the EG nanosheet transistors. |

Integration of air-sensitive two-dimensional materials on arbitrary substrates for the manufacturing of electronic devices
A field-effect transistor and method for fabricating such a field-effect transistor that utilizes an air-sensitive two-dimensional material (e.g., silicene). A film of air-sensitive two-dimensional material is deposited on a crystalized metallic (e.g., Ag) thin film on a substrate (e.g., mica substrate). A capping layer of insulating material (e.g., aluminum oxide) is deposited on the air-sensitive two-dimensional material. The substrate is detached from the metallic thin film/air-sensitive two-dimensional material/insulating material stack structure. The metallic thin film/air-sensitive two-dimensional material/insulating material stack structure is then flipped. The flipped metallic thin film/air-sensitive two-dimensional material/insulating material stack structure is attached to a device substrate followed by having the metallic thin film etched to form contact electrodes. In this manner, the pristine properties of air-sensitive two-dimensional materials are preserved from degradation when exposed to air. Furthermore, this new technique allows safe transfer and device fabrication of air-sensitive two-dimensional materials with a low material and process cost. |

Cyclic etch process to remove dummy gate oxide layer for fin field effect transistor fabrication
Methods are provided to implement a cyclic etch process to remove oxide layers for semiconductor device fabrication. For example, a method comprises performing a cyclic etch process to incrementally etch an oxide layer, wherein the cyclic etch process comprises sequentially performing at least two instances of an etch cycle. The etch cycle comprises performing an etch process to partially etch a portion of the oxide layer using an etch chemistry and environment which is configured to etch down the oxide layer at an etch rate of about 25 angstroms/minute or less, and performing a thermal treatment to remove by-products of the etch process. The cyclic etch process can be implemented as part of a replacement metal gate process to remove a dummy gate oxide layer of a dummy gate structure as part of, e.g., a FinFET semiconductor fabrication process flow. |
