摘要:
A module for a semiconductor chip is disclosed. The module includes a heat sink with a flat surface to which the back face of the semiconductor chip is directly bonded. The exposed face of the chip has an array of power, ground and signal contacts. A plurality of alternating power and ground bus bars span the exposed face of the chip. A multilayer ceramic is located on the other side of the bus bar array and has a surface proximate the power and ground bus bars with an array of contacts which correspond to at least the signal contacts on the chip. Power leads connect the power bus bars to adjacent power contacts on the chip; ground leads connect the ground bus bars to adjacent ground contacts on the chip; and signal leads pass between adjacent power and ground bus bars and interconnect the signal contacts on the chip with the corresponding signal contacts on the ceramic. A plurality of connectors emanate from the ceramic and are electrically coupled by vias or traces through the ceramic to the signal contacts for the transmission of signals to and from the chip.

A semiconductor chip having a two-dimensional array of contacts on an exposed face thereof is mounted in a semiconductor chip module. A mechanism for delivering electricity spans the exposed face of the chip to which it is connected and includes interstitial gaps. A conductor board has a surface proximate the electricity delivering mechanism opposite from the chip. The surface of the board has a two-dimensional array of contacts which correspond to at least some of the contacts on the chip. A biasing mechanism extends from the electricity delivering mechanism toward the exposed face of the semiconductor chip and toward the conductor board, and corresponds to the array of contacts on the chip and board. Signal leads pass through the interstitial gaps and have end portions which extend transversely over the biasing means. The end portions of the signal leads are biased against the contacts of the chips and board by the biasing mechanism.

A module for a semiconductor chip having a front face with a two dimensional array of power, ground and signal contacts is disclosed. Power, ground and signal conductors extend from the respective contacts on the front face of the chip. A pair of electrically conductive plates are parallel to the front face of the chip and located at the termination of the conductors. The plate nearer the conductors is electrically coupled to either the power or ground conductors, and contains apertures corresponding to the remaining ground or power conductors and to the signal conductors. A plurality of discrete signal transmission members are located at a surface of the plate farther from the conductors. The ground or power conductors not connected to the near plate are electrically coupled to the far plate through certain of the apertures, and the signal conductors are coupled to the respective signal transmission members through the remaining apertures.

A circuit structure, and method for forming the structure, permits wafer scale integration by fabricating plural copies of the circuit in integrated circuit form, and interconnecting predetermined circuit element groups of the copies in a manner that permits a majority voting operation to take place. In this manner, defective circuit elements are masked by being out-voted by corresponding non-defective circuit elements that participate in the voting process. Alternate embodiments of a voter unit, used to implement the voting operation, includes a preferred embodiment that takes advantage of emitter-coupled-logic structure to provide a multiplex, voter, latch combination capable of selectively implementing normal and diagnostic operation. Included in the preferred embodiment of the voter unit is a fused link that implements a repair operation in the event there exists more defective circuit element groups than non-defective circuit element groups participating in the voting process.

A method and system for caching content, such as content requested from a server on the World Wide Web. Requests for dynamic content are forwarded directly to a content server to avoid caching data that might only be used once. Requests for static content are forwarded to a hot or a regular cache depending on the frequency at which the content is requested. When a hot cache does not contain the content, it forwards the request to the forwarder which then forwards the request to a regular cache. When the regular cache does not contain the content, it requests the content from the forwarder which then forwards the request to a content server. There may be more than two layers of cache.

A network of microcontrollers for monitoring and diagnosing the environmental conditions of a computer is disclosed. The network of microcontrollers provides a management system by which computer users can accurately gauge the health of their computer. The network of microcontrollers provides users the ability to detect system fan speeds, internal temperatures and voltage levels. The invention is designed to not only be resilient to faults, but also allows for the system maintenance, modification, and growth—without downtime. Additionally, the present invention allows users to replace failed components, and add new functionality, such as new network interfaces, disk interface cards and storage, without impacting existing users. One of the primary roles of the present invention is to manage the environment without outside involvement. This self-management allows the system to continue to operate even though components have failed.
摘要:
A microinstruction-controlled computer including a sequencer for controlling the sequencing of microinstructions. The computer executes target instructions by executing a number of microinstructions for each target instruction. Microinstructions are grouped in one or more microinstruction subroutines in a microstore. Microaddresses for addressing microinstructions and subroutines in the microstore are provided by a microaddress generator which includes a stack unit and other microaddress sources. The stack unit includes a stack memory and a link memory. The link memory stores, for each target instruction, a predetermined number of preloaded microaddresses where each such microaddress specifies the address of one of a number of subroutines employed to execute a particular target instruction. Sequential microaddresses in the link memory are accessed to link the subroutines employed in the execution of each target instruction.

A cooling system for cooling components of a computer is provided. The cooling system includes a DC fan which operates at a speed which is substantially proportional to the voltage that is applied to the fan. A zener diode voltage divider is connected in series between a voltage source and a first input of the fan. The second input of the fan is connected to a reference voltage source. A switch is also connected in series between the voltage source and the first voltage input of the fan so as to be connected in parallel with the zener diode voltage divider. When the switch is in a first position, the voltage produced by the voltage source is applied directly to the fan allowing the fan to operate at a first speed. When the switch is in a second position, the voltage from the voltage source is applied to the first input of the fan through the zener diode such that the first input of the fan receives a second voltage that is less than the first voltage thereby causing the fan to operate at a second speed. The zener diode voltage divider is substantially current independent such that the voltage drop across the zener diode is substantially independent of the current that is drawn by the fan.
