Patent number: 7353357Abstract: A semiconductor memory device has a memory core that includes at least eight banks of dynamic random access storage cells and an internal data bus coupled to the memory core. The internal data bus receives a plurality of data bits from a selected bank of the memory core. The semiconductor memory device further comprises a first interface to receive a read command from external to the semiconductor memory device and a second interface to output first and second subsets of the plurality of data bits. The first subset is output during a first phase of an external clock signal and the second subset is output during a second phase of the external clock signal. The first phase includes a first edge transition and the second phase includes a second edge transition. The second edge transition is an opposite edge transition with respect to the first edge transition.Type: GrantFiled: February 14, 2007Date of Patent: April 1, 2008Assignee: Rambus Inc.Inventors: Richard M.

Patent number: 7330951Abstract: A memory device has interface circuitry and a memory core which make up the stages of a pipeline, each stage being a step in a universal sequence associated with the memory core. The memory device has a plurality of operation units such as precharge, sense, read and write, which handle the primitive operations of the memory core to which the operation units are coupled. The memory device further includes a plurality of transport units configured to obtain information from external connections specifying an operation for one of the operation units and to transfer data between the memory core and the external connections. The transport units operate concurrently with the operation units as added stages to the pipeline, thereby creating a memory device which operates at high throughput and with low service times under the memory reference stream of common applications.Type: GrantFiled: November 8, 2005Date of Patent: February 12, 2008Assignee: Rambus Inc.Inventors: Richard M.

Patent number: 7167039Abstract: A method of operating an integrated circuit including an output driver. The method includes storing a value in a register, wherein the value is representative of a voltage swing setting of an output driver. The voltage swing setting of the output driver is adjusted using a counter that holds a count value representing an update to the voltage swing setting. The count value is updated in accordance with a signal that indicates an adjustment to the voltage swing setting. In addition, an integrated circuit memory device comprising an output driver, a register and a counter is provided. The counter updates a count value in response to a signal that indicates a direction to adjust the count value.Type: GrantFiled: July 14, 2004Date of Patent: January 23, 2007Assignee: Rambus Inc.Inventors: Billy Wayne Garrett, Jr., Nancy David Dillon, legal representative, Michael Tak-Kei Ching, William F.

Patent number: RE39153Abstract: A socket (14) includes a first bus conductor (22a) having two or more contact regions (24) and a second bus conductor (22b) arranged substantially parallel to the first bus conductor and having two or more contact regions (24). The first and second bus conductors are spaced relative to one another so as to provide a predetermined electrical impedance and may be arranged to carry electrical signals as transmission lines. A dielectric spacer (36) may be disposed between the first and second bus conductors to provide the spacing. Contact regions (24) of the first and second conductors (22a, 22b) may provide compliant coupling regions for the socket (14). The contact regions (24) of the first bus conductor (22a) may be positioned within the socket (14) so as to contact a lead disposed on a first side of a circuit element (16) and the contact regions (24) of the second bus conductor (22b) may be positioned within the socket (14) so as to contact the lead disposed on the second side of the circuit element (16).Type: GrantFiled: May 31, 2001Date of Patent: July 4, 2006Assignee: Rambus Inc.Inventors: Donald V.
