  • Patent number: 9230622
    Abstract: A method includes generating a first and a second internal clock signal from a clock signal, wherein a first internal clock signal edge of the first internal clock signal and a second internal clock signal edge of the second internal clock signal are generated from a same edge of the clock signal. A first one of the first and the second internal clock edges is used to trigger a first operation on a six-transistor (6T) Static Random Access Memory (SRAM) cell of a SRAM array. A second one of the first and the second internal clock edges is used to trigger a second operation on the 6T SRAM cell. The first and the second operations are performed on different ports of the 6T SRAM. The first and the second operations are performed within a same clock cycle of the clock signal.

  • Patent number: 8565009
    Abstract: Mechanisms for improving static noise margin and/or reducing misread current in multi-port devices are disclosed. In some embodiments related to dual port SRAM a suppress device (e.g., transistor) is provided at each word line port. When both ports are activated, both suppress devices are on and lower the voltage level of these ports, which in turn lower the voltage level at the node storing the data for the memory. As the voltage level at the data node is lowered, noise margin is improved and read disturb can be avoided.

  • Patent number: 7923988
    Abstract: A test equipment to test power over Ethernet (PoE) function of an Ethernet device comprises a first connector, a second connector, a data signal transmission circuit, a first polarity determination circuit, a second polarity determination circuit and a notification circuit. The first connector receives and transmits data signals and power signals transmitted by the Ethernet device. The data signal transmission circuit transmits the data signals to the second connector and outputs the power signals. The first and second polarity determination circuits receive and output the power signals to the notification circuit. The notification circuit receives the power signals and consequently generates a notice to indicate the PoE function of the Ethernet device is normal.

  • Patent number: 7378655
    Abstract: A method for manufacturing a sensing device, such as a bolometer device or other devices. The method includes providing a substrate, e.g., silicon wafer. The method includes forming a first reflection layer overlying the substrate and forming a first electrode layer overlying the substrate. The method includes forming a sacrificial layer overlying a portion of the first reflection layer and a portion of the first electrode layer. The sacrificial layer is patterned using photolithography techniques. The patterned sacrificial layer corresponds to a cavity region. The method also forms a second electrode layer overlying the sacrificial layer and forms an elastic layer overlying the patterned sacrificial layer. The elastic layer encloses the cavity region corresponding to the patterned sacrificial layer. The method releases the sacrificial layer to form an opening in the cavity region.

  • Patent number: 7336867
    Abstract: A 1×N2 wavelength selective switch (WSS) configuration in which switch elements are configured in a way that enables the input or output fibers to be arranged in a two-dimensional (2D) array. By employing 2D arrays of input/output channels, the channel count is increased from N to N2 for wavelength selective switches. In one embodiment, in which the components are arranged as a 2- ƒ imaging system, a one-dimensional (1D) array of mirrors is configured such that each mirror has a dual scanning axis (i.e., each mirror can be scanned in X and Y directions). In another embodiment, in which the components are arranged as a 4- ƒ imaging system, two 1D arrays of mirrors are configured with orthogonal scanning directions. In both embodiments, the number of ports is increased from N to N2.
