  • Patent number: 7426127
    Abstract: A content-addressable memory circuit includes a first local bit line coupled to a first memory location, a second local bit line coupled to a second memory location, a global bit line coupled to the first and second local bit lines and a global bit line accelerator coupled to the first and second local bit lines and the global bit line. The global bit line accelerator sets the second local bit line to a first logical value depending on a signal from the first local bit line. In this way, the global bit line accelerator accelerates the evaluation phase of operation of the second local bit line.

  • Publication number: 20080160671
    Abstract: A method of forming a packaging structure and the packages formed thereof are provided. The method includes providing a package having a top surface and placing solder balls on the top surface of the package. A coplanar surface is then placed against the solder balls, wherein the surface is non-adhesive. A reflow process is performed to the solder balls, so that top surfaces of the solder balls are substantially coplanar. The coplanar surface is then removed.

  • Publication number: 20070265550
    Abstract: A venous-arterial detector is disclosed. The detector includes a first chamber in fluid communication with a needle, and an indicator chamber in selective fluid communication with the first chamber through a valve. The indicator chamber is pre-pressurized to a defined pressure that preferably exceeds typical venous pressure, and the valve retains that pressure within the indicator chamber. When the needle is inserted into a vessel, if the pressure in the vessel is greater than the defined pressure in the indicator chamber, blood will flow into the indicator chamber, indicating that the vessel is most likely to be an artery.

  • Patent number: 7161826
    Abstract: A memory circuit includes a word line, a data storage circuit including one or more memory cells or sub-cells, and an inverter coupled between the word line and the N memory cells. The inverter inverts a word-line signal input into a read port of the cells or sub-cells. Because the word-line inverter is local to each cell or sub-cell, DC offset is substantially reduced which translates into a reduction in leakage current.

  • Publication number: 20060067136
    Abstract: A device includes a number of memory cells. Each of the memory cells includes a transistor stack coupled to a bit line. A value of a charge on the bit line during an access mode represents a value of data stored in an accessed memory cell. During a non-access mode, all transistors of the transistor stack are turned off to save power. The transistors are turn off regardless of the value of the data stored in the memory cells.

  • Publication number: 20060044013
    Abstract: A logic circuit performs an internal level conversion function by driving portions of the circuit with different supply voltages. In one embodiment, first and second stage storage circuits are driven with different supply voltages. In another embodiment, first and second stage storage circuits are driven with a first supply voltage and an inverter coupled to the first stage storage circuit is driven with a second supply voltage. In either case, data transfer into the storage circuits may be controlled by different states of a clock signal. The logic circuit may be a flip-flop circuit, a latch circuit, or another type of circuit.
