  • Publication number: 20120297080
    Abstract: Aspects of the subject matter described herein relate to stream operators. In aspects, a stream event is received. Based on a timestamp associated with the stream event and the number of stream operators that have asked to be activated prior to or at the timestamp, zero or more stream objects are informed of one or more time events and torn down if no longer needed. In addition, a destination stream operator is instantiated, if needed, data (e.g., the timestamp and packet, if any) corresponding to the stream event is provided to a stream operator, output data, if any, is received from the stream operator, and the stream operator is torn down if it no longer needs state data between invocations.

  • Patent number: 8228714
    Abstract: In a particular embodiment, a memory device is disclosed that includes a memory cell including a resistance-based memory element coupled to an access transistor. The access transistor has a first oxide thickness to enable operation of the memory cell at an operating voltage. The memory device also includes a first amplifier configured to couple the memory cell to a supply voltage that is greater than a voltage limit to generate a data signal based on a current through the memory cell. The first amplifier includes a clamp transistor that has a second oxide thickness that is greater than the first oxide thickness. The clamp transistor is configured to prevent the operating voltage at the memory cell from exceeding the voltage limit.

  • Patent number: 8199602
    Abstract: Reduction of line delay is accomplished in an electronic memory by segmenting portions of the memory and only enabling certain memory portions depending upon where the memory is to be accessed. In one embodiment, the bit lines are segmented using latch repeaters to control the bit line length for address selection. The latch repeaters are, in one embodiment, allowed to remain in their operated/non-operated state at the completion of a memory read/write cycle. This then avoids successive enabling pulses when the same segment is accessed on successive cycles.
