    Abstract: A sensing circuit includes a sensing resistor, a reference resistor and a comparator. The comparator has a first input coupled to the sensing resistor, a second input coupled to the reference resistor, and an output. The first input is configured to be coupled to a data bit line associated with a memory cell to receive a sensing input voltage caused by a cell current of the memory cell flowing through the sensing resistor. The second input is configured to be coupled to a reference bit line associated with a reference cell to receive a sensing reference voltage caused by a reference current of the reference cell flowing through the reference resistor. The comparator is configured to generate, at the output, an output signal indicating a logic state of data stored in the memory cell based on a comparison between the sensing input voltage and the sensing reference voltage.

  • Publication number: 20160181633
    Abstract: A complex fuel cell stack with hydrogen storage unit is introduced. Through the new configuration of the PEM fuel cell stack, no cooling system and cooling fluid is needed for the fuel cell stack, since hydrogen storage vessel can act as a heat sink to protect the expensive catalyst layer of the MEA of the fuel cell away from over-heated and damaged. In addition, the waste heat generated from the operation of the fuel cells can aid in release of hydrogen from hydrogen storage alloys inside the hydrogen storage vessel.

  • Patent number: 9348965
    Abstract: A method for circuit design includes a parasitic aware library embedded with one or more parameterized cells. The parasitic aware library is used to insert nets representing some but not all parasitic effects of a circuit into a circuit schematic enabling a single circuit schematic to be used for simulation of the circuit, parasitic verification of the circuit and LVS (Layout Versus Schematic) check. Only the single circuit schematic is required for the circuit design process and to form a mask set. Critical paths of the single circuit schematic are identified and parasitic effects are extracted and inserted into the schematic, enabling a pre-estimation of parasitic verification to be carried out and the LVS check to be carried out using a circuit schematic with some parasitic effects prior to the post-layout simulation in which all parasitic components of the layout are included.

  • Publication number: 20150356917
    Abstract: A current value of a first pixel and/or a current value of a second pixel of a display are adjusted until a value of a current difference is within a predetermined range. The current value of the first pixel corresponds to a brightness level of the first pixel. The current value of the second pixel corresponds to a brightness level of the second pixel. Adjusting the current value of the first pixel involves adjusting a threshold voltage value of a transistor of the first pixel. Adjusting the current value of the second pixel involves adjusting a threshold voltage value of a transistor of the second pixel.

  • Patent number: 8957482
    Abstract: In various embodiments, the fuse is formed from silicide and on top of a fin of a fin structure. Because the fuse is formed on top of a fin, its width takes the width of the fin, which is very thin. Depending on implementations, the fuse is also formed using planar technology and includes a thin width. Because the width of the fuse is relatively thin, a predetermined current can reliably cause the fuse to be opened. Further, the fuse can be used with a transistor to form a memory cell used in memory arrays, and the transistor utilizes FinFET technology.
