Publication number: 20080048835Abstract: A radio frequency identification device includes an integrated circuit including a receiver, a transmitter, and a microprocessor. The receiver and transmitter together define an active transponder. The integrated circuit is preferably a monolithic single die integrated circuit including the receiver, the transmitter, and the microprocessor. Because the device includes an active transponder, instead of a transponder which relies on magnetic coupling for power, the device has a much greater range.Type: ApplicationFiled: August 29, 2007Publication date: February 28, 2008Inventors: James O'Toole, John Tuttle, Mark Tuttle, Tyler Lowrey, Kevin Devereaux, George Pax, Brian Higgins, David Ovard, Shu-Sun Yu, Robert Rotzoll

Publication number: 20080036492Abstract: A registered memory module includes several memory devices coupled to a register through a plurality of transmission lines forming a symmetrical tree topology. The tree includes several branches each of which includes two transmission lines coupled only at its ends to either another transmission line or one of the memory devices. The branches are arranged in several layers of hierarchy, with the transmission lines in branches having the same hierarchy having the same length. Each transmission line preferably has a characteristic impedance that is half the characteristic impedance of any pair of downstream transmission lines to which it is coupled to provide impedance matching. A dedicated transmission line is used to couple an additional memory device, which may or may not be an error checking memory device, to the register.Type: ApplicationFiled: October 9, 2007Publication date: February 14, 2008Applicant: Micron Technology, Inc.Inventors: George Pax, Roy Greeff

Publication number: 20070099443Abstract: Memory modules and methods for manufacturing memory modules are disclosed herein. In one embodiment, a memory module includes a substrate, a microelectronic device carried by the substrate, and a plurality of external contact pads operably coupled to the microelectronic device. The substrate includes a first major surface with a first longitudinal edge and a second longitudinal edge. The external contact pads are disposed on the first major surface proximate to the second longitudinal edge. The contact pads include a first contact pad with a first end proximate to the second longitudinal edge and a second contact pad with a second end proximate to the second longitudinal edge. The first end is spaced apart from the first longitudinal edge by a first distance, and the second end is spaced apart from the first longitudinal edge by a second distance different than the first distance.Type: ApplicationFiled: December 21, 2006Publication date: May 3, 2007Applicant: Micron Technology, Inc.Inventor: George Pax

Publication number: 20060203938Abstract: A method and system for generating a reference voltage for memory device signal receivers operates in either a calibration mode or a normal operating mode. In the calibration mode, the magnitude of the reference voltage is incrementally varied, and a digital signal pattern is coupled to the receiver at each reference voltage. An output of the receiver is analyzed to determine if the receiver can accurately pass the signal pattern at each reference voltage level. A range of reference voltages that allow the receiver to accurately pass the signal pattern is recorded, and a final reference voltage is calculated at the approximate midpoint of the range. This final reference voltage is applied to the receiver during normal operation.Type: ApplicationFiled: May 11, 2006Publication date: September 14, 2006Inventors: Brent Keeth, Joo Choi, George Pax, Ronnie Harrison, David Ovard, Dragos Dimitriu, Troy Manning, Roy Greeff, Greg King, Brian Johnson

Publication number: 20060028904Abstract: A registered memory module includes a plurality of flip-flops having respective data terminals, respective clock terminals receiving a clock signal and output terminals coupled to a plurality of SDRAM devices in the module. A logic gate decodes respective chip select signals for selecting the SDRAM devices. The logic gate generates an enable signal if a memory access is being directed to any of the SDRAM devices in the module. In one embodiment, the flip-flops include an enable input coupled to receive the enable signal from the logic gate. In another embodiment, the input signals are coupled to the data inputs of the flip-flops through logic gates that are selectively enabled by the enable signal from the logic gate. As a result, the input signals are not latched by transitions of the clock signal when a memory access is not directed to any of the SDRAM devices in the module.Type: ApplicationFiled: August 12, 2005Publication date: February 9, 2006Inventor: George Pax

Publication number: 20050172069Abstract: A computer system provides improved routability for memory modules. Chips are placed on the back side of the module directly behind the chips on the front side, and vias connects destination pins on the front side to the back side. Internal assignments are routed to the pins so as to be bilaterally symmetrical. These functions can include any of the pins used on the memory chip, including the address bus and the command bus. The bit positions of the internal assignments routed to pins connected together need not be identical. Where bit positions are coupled together, a remap multiplexer is used to perform rerouting of logical information onto different physical bus lines. The remap multiplexer may be implemented in the system BIOS, in the memory controller, or alternatively on the memory module. Further, the rerouting may be accomplished through any combination of hardware or software.Type: ApplicationFiled: March 28, 2005Publication date: August 4, 2005Inventor: George Pax
