  • Patent number: 8391099
    Abstract: An integrated circuit memory device, system and method embodiments decode interleaved row and column request packets transferred on an interconnect at a first clock frequency. Separate row decode logic and column decode logic, clocked at a relatively slower second clock frequency, output independent column and row control internal signals to a memory core in response to memory commands in the request packets. An integrated circuit memory device includes an interface having separate row and column decode logic circuits for providing independent sets of row and control signals. A row decode logic circuit includes a first row decode logic circuit that provides a first row control signal, such as a row address, and a second row decode logic circuit that provides a second row control signal. A column decode logic circuit includes a first column decode logic circuit that provides a first column control signal, such as a column address and a second column logic circuit that provides a second column control signal.

  • Publication number: 20110238870
    Abstract: A memory system includes a memory controller coupled to at least one memory device via high-speed data and request links. The timing and voltage margins of the links are periodically calibrated to reduce bit error. The high-speed request links complicate calibration because commands issued over the uncalibrated request links can be erroneously interpreted by the memory device. Misinterpreted commands can disrupt the calibration procedure (e.g., a write command might be misinterpreted as a power-down command). The memory controller addresses this problem using a separate, low-speed control interface to issue a filter command that instructs the memory device to decline potentially disruptive requests when in a calibration mode.

  • Patent number: 7461852
    Abstract: The invention includes a step device for assisting entry into and/or exit from a vehicle such as, for example, high road clearance truck. The step device comprises a generally “W” shaped bar which is separable into said two generally “U” shaped elements for easier packaging, shipping and manipulation of the device. Each of the “U” shaped elements include a cross-bar fixedly attached between, and spanning across, an interior of the generally “U” shaped element. The cross-bars are configured for separately mounting to the vehicle such that the generally “U” shaped elements are independently supported and the generally “U” shaped elements may be adjustable to multiple angles with respect to said vehicle.

  • Publication number: 20060039227
    Abstract: A memory system includes logical banks divided into sub-banks or collections of sub-banks. The memory system responds to memory-access requests (e.g., read and write) directed to a given logical bank by sequentially accessing sub-banks or collections of sub-banks. Sequential access reduces the impact of power-supply spikes induced by memory operations, and thus facilitates improved system performance. Some embodiments of the memory system combine sequential sub-bank access with other performance-enhancing features, such as wider power buses or increased bypass capacitance, to further enhance performance.

  • Publication number: 20050276261
    Abstract: A method for calibrating a communication channel coupling first and second components includes transmitting a data signal from the first component to the second component on the communication channel, and sensing a characteristic, such as phase, of the data signal on the second component. Information about the sensed characteristic is fed back to the first component using an auxiliary channel. An adjustable parameter, such as phase, for the transmitter is adjusted on the first component in response to the information. Also, a characteristic of a data signal received from the transmitter on the second component is sensed and used to adjust an adjustable parameter for the receiver on the first component.
