摘要： 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.

摘要： 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.

摘要： 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.

摘要： A method of forming an integrated circuit including a Schottky diode includes providing a substrate of a first conductivity type, defining a region of a second conductivity type relative to the substrate and forming an insulator over the second conductivity type region. The method also includes removing an area of the insulator for definition of a contact hole, and removing an area encircling the contact hole and forming highly doped regions of the second conductivity type in second conductivity type regions encircling the contact hole. The method further includes depositing a Schottky metal in the contact hole and annealing the metal to form a suicide interface to the second conductivity type region.

摘要： One or more interrogating commander stations and an unknown plurality of responding responder stations coordinate use of a common communication medium. Each commander station and each responder station is equipped to broadcast messages and to check for error in received messages. When more than one station attempts to broadcast simultaneously, an erroneous message is received and communication is interrupted. To establish uninterrupted communication, a commander station broadcasts a command causing each responder station of a potentially large first number of responder stations to each select a random number from a known range and retain it as its arbitration number. After receipt of such a command, each addressed responder station transmits a response message containing its arbitration number. Zero, one, or several responses may occur simultaneously. By broadcasting requests for identification to various subsets of the full range of arbitration numbers and checking for an immediate error-free response, a commander station can determine the arbitration number of every responder station capable of communicating at the time. Consequently, a commander station can conduct subsequent uninterrupted communication with each responder station, for example by addressing only one responder station. Responder stations of this invention -require minimal logic and circuitry to respond to multiple commander stations.
