    摘要: A single logic gate array chip (1) is disclosed having a first portion (2) dedicated to the generation of one or more clock signals and the remaining portion (3) occupied by logic circuits. The first portion (2) uses the same gate array cell design as embodied in the logic circuits of the remaining portion (3). Both portions are powered by similar gate array metallization patterns, although some of the cells of the clock signal sources are disconnected from the normal chip powering busses and are powered instead by respective control signal generators. Each control signal represents the frequency difference between a given clock signal and a reference signal. The cells which are powered by a given control signal introduce a commensurate signal delay to drive the clock signal frequency into a predetermined relationship with the frequency of the reference signal.

    摘要: A circuit and method for generating a read complete signal for a high speed densely packaged monolithic memory is disclosed. The memory (34) is designed to utilize and externally generated ad­dress valid signal which indicates that the address to the memory is valid. The receipt of the address valid signal sets a set/­reset latch (18) and starts the memory (34). The addressed memory cells are sensed. When at least one memory cell has data are its output below a threshold, the data are said to be un­stable and the set/reset latch is then conditioned to be reset. When the data sensed by all the sensing circuits (36) are stable, a signal (ADV) is sent to the set/reset latch (18) to cause it to be reset. The resetting of the set/reset latch (18) causes an output thereof ot change state. This state change comprises the read complete signal (RC) which is used to determine the read cycle time of the memory and may also be used in diagnostic tests of the memory.

    摘要: A process is described which permits the fabrication of very narrow base width bipolar transistors in selected areas of an integrated circuit chip and bipolar transistors of wider base width on other selected areas of the same integrated circuit chip. The ability to selectively vary the transistor characteristics from one region of an integrated circuit chip to another provides a valuable degree of freedom for design of integrated circuits. The bipolar transistors on an integrated circuit chip are processed up to the point of emitter formation using conventional techniques. But, prior to the emitter (34, 35) formation, the base area (22) which is to be the emitter (34) of the selected region havingthe very narrow base transistors is dry etched using reactive ion etching. The existing silicon nitride/silicon dioxide layers with the emitter opening therein are used as the etching mask for this reactive ion etching procedure. Once the etching is completed to the desired depth, the normal processing is resumed to form the emitters (34, 35) and rest of the metallization.

    摘要: Zum Angleichen der unterschiedlichen Signalverzögerungszeiten der Logik-Gatter verschiedener Halbleiterchips ist auf jedem Halbleiterchip eine Regelschaltung (4) für die Signalverzögerung vorgesehen. Ihr wird als Bezugssignal ein externer, allen Halbleiterchips gemeinsamer Taktimpuls zugeführt. Die Regelschaltung vergleicht dessen Phasenlage mit der eines Impulszuges, der von einem zur Regelschaltung gehörenden spannungsgesteuerten Oszillator geliefert wird. Die als Vergleichsergebnis erhaltene und verstärkte Spannung beeinflußt den spannungsgesteuerten Oszillator, bis die beiden Impulszüge synchronisiert sind. Die verstärkte Spannung wird auch den Logik-Gattern zugeführt. Sie verändert deren Aufnahme von elektrischer Leistung so, daß die gewünschte Signalverzögerung, die eine Funktion der elektrischen Leistung ist, erreicht wird.
