  • Patent number: 7716619
    Abstract: A keeper device design structure for dynamic logic used in integrated circuit designs includes a first keeper path statically coupled to a dynamic data path, the first keeper path configured to prevent false discharge of the dynamic data path during an evaluation thereof, and a second keeper path selectively coupled to the dynamic data path. The second keeper path is configured to maintain the dynamic data path at a nominal precharge level prior to an evaluation thereof, wherein the second keeper path is decoupled from the dynamic data path during the evaluation.
    Type: Grant

  • Publication number: 20080055956
    Abstract: A design structure for content addressable memory including a first array of memory cells, and a second array of memory cells. A search logic circuit is configured to prevent a discharge of the second array of memory cells when a search of the first array of memory cells finds certain data.

  • Publication number: 20080002497
    Abstract: A method for small signal sensing during a read operation of a static random access memory (SRAM) cell includes coupling a pair of complementary sense amplifier data lines to a corresponding pair of complementary bit lines associated with the SRAM cell, and setting a sense amplifier so as to amplify a signal developed on the sense amplifier data lines, wherein the bit line pair remains coupled to the sense amplifier data lines at the time the sense amplifier is set. Also provided is a design structure embodied in a machine readable medium used in a design process.

  • Patent number: 6262911
    Abstract: A method to statically balance Silicon-On-Insulator (SOI) parasitic effects is disclosed. Additionally, eight device Static Random Access Memory (SRAM) cells using the method are provided. A balanced output stage that creates a particular set of parasitic effects, as seen by a node connected to the output of the balanced output stage, is provided. If the balanced output stages are used at both outputs of a SRAM cell, the nodes to which the outputs of the balanced output stages are connected will see the same parasitic effects when the transistors in the balanced output stages are off. Thus, the balanced output stages can create the same effect on both the true and complement bitlines of an SOI SRAM, thereby balancing both of these lines and improving access times.
