In an embodiment, a memory device includes a memory array and circuitry, coupled thereto, to perform data computations based on the data stored at the memory array. Based on instructions received at the memory device, control circuitry is configured to enable an automatic performance of a sequence of operations. In another embodiment, the memory device is coupled in an in-series arrangement of other memory devices to provide a pipeline circuit architecture. The memory devices each function as a respective stage of the pipeline circuit architecture, where the stages each perform respective in-memory computations.

摘要： A positive displacement fluid flow meter comprises a chamber having a fluid inlet and a fluid outlet. A rotor is displaceable within the chamber, rotation of the rotor being related to the volume of fluid passing through the chamber. The chamber has a surface proximate which an end surface of the rotor passes, the chamber surface and/or the rotor end surface having at least one recess to retain at least a portion of debris carried by the metered fluid. The recess is preferably formed so as not to provide fluid, communication, from the inlet to the outlet across the rotor end surface. A lid closes an end of the chamber which in use is subject to the pressure of fluid within the chamber. The lid is engaged at its periphery to a wall of the chamber, and is preferably flexible adjacent its periphery to reduce the transmission of bending stresses between the periphery of the lid and the remainder thereof.

摘要： A detuned duo-cavity laser-modulator device and method are provided which include lower, middle and upper reflectors, a gain region and an absorber region integrated into a semiconductor die. The middle reflector is disposed between the lower and upper reflectors. Together, the lower and middle reflectors define a first resonant cavity, while the upper and middle reflectors define a second resonant cavity. A gain region is disposed within a laser cavity of the resonant cavities to generate an optical carrier wave, while an absorber region is disposed within a modulator cavity of the resonant cavities to modulate a signal on the optical carrier wave. The laser and modulator cavities are detuned resonant cavities, with the detuning of the laser and modulator cavities being selected to minimized change in reflection from the modulator cavity to the laser cavity when the absorber region modulates the signal on the optical carrier wave.

摘要： A clock receiver architecture for source synchronous digital data communication, the receiver including a forwarded clock amplifier to provide the received forwarded clock signal to a plurality of delay locked loops. Each delay locked loops provides to one or more phase interpolators a set of clock signals generated from the received forwarded clock, where the relative phases of the set of clock signals are uniformly spaced. Phase interpolators interpolate between two adjacent (with respect to phase) clock signals so as to provide a clock signal to sample received data at the center of the data eye. In some embodiments, an on-die voltage regulator provides a regulated supply voltage to the delay locked loops and phase interpolators. In some embodiments, pull-up currents and pull-down currents in the phase locked loops and phase interpolators are matched across process, supply voltage, and temperature variations so that the relative phases of the clock signals are insensitive across process, supply voltage, and temperature variations. Other embodiments are described and claimed.
