  • Publication number: 20150365080
    Abstract: According to an embodiment, a method of generating a clock pulse includes receiving a leading edge at a clock input at a time when an enable signal is active, generating an edge at a clock output based on the received leading edge at the clock input, latching a logic value corresponding to the edge at the clock output, preventing changes at the clock input from affecting the latched logic value after the logic value is latched, resetting the latched logic value after a first delay time, and maintaining the reset logic value until a second edge is received at the clock input. The second edge at the clock input matches the leading edge at the clock input.

  • Patent number: 9165642
    Abstract: A memory cell includes a latch having a true data node and a complement data node, a true bitline, a complement bitline, a first access transistor coupled between the true bitline and the true data node, and a second access transistor coupled between the complement bitline and the complement data node. A wordline driver circuit includes a true wordline coupled to control the first access transistor and a complement wordline coupled to control the second access transistor. The wordline driver generates control signals on the true and complement wordlines to access the memory cell by: actuating the first access transistor while the second access transistor is not actuated and then actuating the second access transistor while the first access transistor is not actuated. The bitlines and wordlines are supplied from different sets of power supply voltages, with the bitline high supply voltage being less than the wordline high supply voltage.

  • Patent number: 9147453
    Abstract: Delays are introduced in self-timed memories by introducing a capacitance on the path of a signal to be delayed. The capacitances are realized by using idle-lying metal layers in the circuitry. The signal to be delayed is connected to the idle-lying capacitances via programmable switches. The amount of delay introduced depends on the capacitance introduced in the path of signal, which in turn depends on state of the switches. The state of the switches is controlled by delay codes provided externally to the delay introducing circuitry. Since idle-lying metal capacitances are utilized, the circuitry can be implemented using a minimum amount of additional hardware. Also, the delay provided by the circuitry is a function of memory cell SPICE characteristics and core parasitic capacitances.

  • Publication number: 20150269262
    Abstract: A method for retrieving information includes determining, by the information retrieval management computing device, when an identified subject of interest in a received query maps to one of one or more ontology entities. An identification is made, by the information retrieval management computing device, when the identified subject of interest is one of one or more existing subjects of interest when the identified subject of interest is determined to map to one of the ontology entities. One or more filters associated with the identified subject of interest are stored by the information retrieval management computing device.

  • Publication number: 20150195156
    Abstract: A method and system for providing page visibility information are provided herein. Aspects of this disclosure provide an interface by which a browser may make the visibility state of a particular page available to the page itself. The browser may track the visibility state of the page as it changes and store the state in a variable associated with the page. Code executing within the page may query this variable to determine the visibility state and take appropriate action. The browser may provide an application programming interface (API) to allow the page to request the visibility state.

  • Patent number: 9006841
    Abstract: A dual port SRAM has two data storage nodes, a true data and complementary data. A first pull down transistor has an active area that forms the drain region of the first transistor and the true data storage node that is physically isolated from all other transistor active areas of the memory cell. A second pull down transistor has an active area that forms the drain region of a second transistor that is the complementary data node that is physically isolated from all other transistor active areas of the memory cell.

  • Publication number: 20150029795
    Abstract: A write is performed to a first cell of a memory at a first row and column during a first memory access cycle. A memory access operation is made to a second cell at a second row and column during an immediately following second memory access cycle. If the memory access is a read from the second cell and the second row is the same as the first row, or if the memory access is a write to the second cell and the second row is the same as the first row and the second column is different than the first column, then a simultaneous operation is performed during the second memory access cycle. The simultaneous operation is an access of the second cell (for read or write) and a re-write of data from the first memory access cycle write operation back to the first cell.
