  • Patent number: 8352772
    Abstract: A memory system includes a memory controller that issues command signals and a reference-clock signal to a memory device. The edge rate of the reference-clock signal is lower than the bit rate of the command signals, so the memory device multiplies the reference clock signal to develop a command-recovery clock signal with which to sample the incoming command signals. The memory controller issues the command signals as a series of multi-bit command words aligned with edges of the reference-clock signal so that the memory device can use edges of the reference clock signal for command-word alignment.

  • Patent number: 8341286
    Abstract: A host with a network interface that offloads a TCP connection is disclosed in which the notification that relatively small data transmit commands have completed is batched whereas the notification that relatively large data transmit commands have completed are not batched. The notification that data transmit commands have completed may be intrinsically modulated by the size and frequency of the commands and the processing of the data transfer by the TCP connection. One embodiment involves a method comprising: running an application on a computer having a network interface; running, on the network interface, a TCP connection for the application; providing, by the computer to the network interface, a command to send data from the application; updating, by the network interface, a SndUna value for the TCP connection; and providing, by the network interface to the computer, the SndUna value, thereby indicating to the computer that the command has been completed.

  • Patent number: 8310294
    Abstract: A communication IC includes a power-efficient clock-distribution system. A control loop monitors and adjusts the peak and trough voltages of a clock signal. The clock signal can be adaptively adjusted to center the peak and trough voltages about the switching threshold voltage of a clock buffer. The voltage swing of the clock signal can thus be made small and, as a consequence, power efficient. The control loop can monitor and control more than one clock signal.

  • Patent number: 8305821
    Abstract: A memory system includes a memory controller that writes data to and reads data from a memory device. A write data strobe accompanying the write data indicates to the memory device when the write data is valid, whereas a read strobe accompanying data from the memory device indicates to the memory controller when the read data is valid. The memory controller adaptively controls the phase of the write strobe to compensate for timing drift at the memory device. The memory controller uses the read strobe as a measure of the drift.

  • Patent number: 8305871
    Abstract: Described are methods and circuits for reducing the error-inducing effects of crosstalk. Communication circuits in accordance with some embodiments adjust the phase of transmitted “aggressor” data to misalign transmitted signals from the perspective of “victim” channels. This misalignment moves the noise artifacts cross coupled to the victim channel away from sensitive sample times in the victim data, and consequently reduces the net effects of aggressor crosstalk on neighboring victim channels. Some embodiments reduce the effects of crosstalk by introducing static timing offsets to one or a plurality of aggressor transmitters, one or a plurality of victim transmitters, or some combination of aggressor and victim transmitters. Other embodiments dynamically alter the relative timing of aggressor and victim transmitters.

  • Patent number: 8298329
    Abstract: Unlike conventional dental ceramic powder made by grinding, dental ceramic nanocrystals are formed by vaporization into individual particles. Tetragonal zirconia particles thus formed are not broken into pieces, and so do not transform to weaker monoclinic zirconia and weaker sintered products. The particles created by this approach can be much smaller, and dental prostheses sintered from this powder can be stronger and more realistic. For instance, the smaller size of sintered tetragonal zirconia crystals increases optical translucence by reducing scattering from birefringence, and the small average particle size and tight distribution of sizes and shapes can essentially eliminate pores in a sintered product. Cylindrical and spherical particles can be manufactured by this approach, whereas prior art dental ceramic particles were generally neither.

  • Patent number: 8283896
    Abstract: An energy storage device includes buck and boost switches that charge and discharge a charge storage element (e.g. a supercapacitor or ultracapacitor) over a broad voltage range. Integrated charge limiting prevents the storage element from sinking a potentially damaging level of current. Pulse-width modulated control signals are combined with higher-frequency signals to allow the resulting modulated control signals to pass through relatively small, inexpensive isolation transformers. Pairs of control signals may be combined to produce composite control signals that turn power switches on and off, or may be used to separately turn the power switches on and off.

  • Patent number: 8281055
    Abstract: Described are memory modules that support dynamic point-to-point extensibility using fixed-width memory die. The memory modules include data-width translators that allow the modules to vary the effective width of their external memory interfaces without varying the width of the internal memory interfaces extending between the translators and associated fixed-width dies. The data-width translators use a data-mask signal to selectively prevent memory accesses to subsets of physical addresses. This data masking divides the physical address locations into two or more temporal subsets of the physical address locations, effectively increasing the number of uniquely addressable locations in a given module. Reading temporal addresses in write order can introduce undesirable read latency. Some embodiments reorder read data to reduce this latency.

  • Patent number: 8278968
    Abstract: Described are on-die termination (ODT) systems and methods that facilitate high-speed communication between a driver die and a receiver die interconnected via one or more signal transmission lines. An ODT control system in accordance with one embodiment calibrates and maintains termination resistances and drive currents to produce optimal output swing voltages. Comparison circuitry employed to calibrate the reference resistance is also used to calibrate the drive current. Termination elements in some embodiments are divided into two adjustable resistive portions, both of which are designed to minimize capacitive loading. One portion is optimized to produce a relatively high range of adjustment, while the other is optimized for fine-tuning and glitch-free switching.

  • Patent number: 8243783
    Abstract: An integrated receiver supports adaptive receive equalization. An incoming bit stream is sampled using edge and data clock signals derived from a reference clock signal. A phase detector determines whether the edge and data clock signals are in phase with the incoming data, while some clock recovery circuitry adjusts the edge and data clock signals as required to match their phases to the incoming data. The receiver employs the edge and data samples used to recover the edge and data clock signals to note the locations of zero crossings for one or more selected data patterns. The pattern or patterns may be selected from among those apt to produce the greatest timing error. Equalization settings may then be adjusted to align the zero crossings of the selected data patterns with the recovered edge clock signal.

  • Patent number: 8235558
    Abstract: An artificial candle has a delicate glowing shroud or sock that can flutter like a candle flame, and the shroud may surround a “wick” that can be seen through the shroud to glow. Such a diaphanous shroud can be actuated by a fan, air pump, solenoid or conductor, which can be provided adjacent to the shroud or distanced from the shroud, for example in a central body of a chandelier. The wick may be lighted by a light emitting diode (LED), and the shroud can include fluorescent material that absorbs and reradiates some of the light from the wick. The wick and the shroud can be coupled to a shaft that simulates a wax candle body. A standard threaded fitting can be provided so that the artificial candle can thread into a socket to replace a light bulb.

  • Patent number: 8208595
    Abstract: An apparatus that reduces sampling errors for data communicated between devices uses phase information acquired from a timing reference signal such as a strobe signal to align a data-sampling signal for sampling a data signal that was sent along with the timing reference signal. The data-sampling signal may be provided by adjustably delaying a clock signal according to the phase information acquired from the strobe signal. The data-sampling signal may also have an improved waveform compared to the timing reference signal, including a fifty percent duty cycle and sharp transitions. The phase information acquired from the timing reference signal may also be used for other purposes, such as aligning received data with a local clock domain, or transmitting data so that it arrives at a remote device in synchronism with a reference clock signal at the remote device.
