Patent number: 9230622Abstract: 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.Type: GrantFiled: November 30, 2012Date of Patent: January 5, 2016Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Ching-Wei Wu, Chia-Cheng Chen, Kuang Ting Chen, Wei-Shuo Kao, Jui-Che Tsai

Patent number: 8565009Abstract: 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.Type: GrantFiled: April 27, 2010Date of Patent: October 22, 2013Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Ching-Wei Wu, Lee Cheng Hung, Hung-Je Liao, Jui-Che Tsai

Patent number: 7378655Abstract: 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.Type: GrantFiled: April 9, 2004Date of Patent: May 27, 2008Assignee: California Institute of TechnologyInventors: Yu-Chong Tai, Matthieu Liger, Ming C.

Patent number: 7336867Abstract: 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.Type: GrantFiled: May 30, 2006Date of Patent: February 26, 2008Assignee: The Regents of the University of CaliforniaInventors: Ming-Chiang Wu, Jui-Che Tsai
