    摘要: A current limiting driver circuit (10) receives a first logic level input signal (O &cir& /1) and drives an output pin (26). A node (14) is pulled to ground by a pull-down transistor (16) which receives the first input signal (O &cir& /1) and is driven to a high voltage state by a pull-up transistor (12). A driver transistor (28) is turned on by a high voltage state at the node (14) and is turned off by a low voltage state at the node (14). The driver transistor (28) is connected to provide a high voltage state to the output pin (26). A pull-down transistor (30) is connected to receive the first input signal (O &cir& /1) in order to pull the output pin (26) to ground. A series of transistors (18, 20, 22) are connected between the gate and source terminals of the driver transistor (28) such that when the gate-to-source voltage of the driver transistor (28) exceeds the combined thresholds of the three transistors (18, 20, 22) they will by turned on and thereby limit the maximum gate-to-source voltage of driver transistor (28). This in turn serves to limit the maximum current flow through the driver transistor (28). Disabling transistors (17, 32) are included for providing a high impedance output to the output pin (26).

    摘要: A power distribution network for an integrated circuit is fabricated together with the circuit on a silicon substrate (10). The silicon substrate (10) is fabricated to form diffusion regions (50) as part of the active devices in the integrated circuit. A dielectric separation layer (51) is fabricated over the surface of substrate (10). Above the region (50) there is fabricated a power distribution line (52) comprising a metallization of aluminum or aluminum-alloy material. A passivation layer (54) is formed over the dielectric layer (51) and the conductor (52) but is opened above the central region of the conductor (52). An adhesion and diffusion barrier layer (58) is fabricated over the conductor (52) and passivation layer (54). Above the layer (58) there is fabricated a thick layer of metallization (60) in the form of a conductor strip configured similar to the underlying conductor layer (52). The conductive layers (58, 60) are etched to have essentially the same width as the conductor line (52). The conductive layers (58 and 60) can optionally be made to have a greater width than the underlying layer as is illustrated by the conducting layers (76, 78).

    摘要: A dual-tone multi-frequency (DTMF) tone generator circuit (10) produces selected frequency row and column tones which are combined to generate a DTMF signal. Key board scan circuits (42, 44) scan a conventional push-button telephone key board to produce row and column input signals. Row and column fundamental rate signals are generated by fundamental counters (48, 76) from a reference signal derived from an external crystal (12). Row and column integration rate signals are generated by integrator counters (50, 78) also derived from the reference signal. Specialized row and column clock control signals (SLOPE RATE, SLOPE SIGN, AUTO ZERO) are produced by clock generators (58, 82). Row and column integrators (64, 92) integrate reference signals to produce discrete voltage steps at the rate of the row and column integration rate signals to produce row and column signals made up of a plurality of segments for each cycle of the signal. Each signal segment comprises a plurality of similar voltage steps having amplitude and polarity determined by the specialized row and column clock signals (SLOPE RATE, SLOPE SIGN). The row and column signals are combined in a summer (68) to produce the DTMF signal.

    摘要: Electronic circuit package (10) for encapsulating and interconnecting two or more semiconductor chips (44A). A vertically stacked array of substrate wafers form a support core (12) in which windows (14, 16, 18, 20) are formed for receiving the chips. Device support surfaces and device lead connecting surfaces (70, 72) are exposed by each cavity on one or more of the substrate wafers. Intra-level conductive strips (74) are separately deposited on each lead connecting surface for attachment to the input/output leads (42) of the circuit devices and extend along the interface of one or more superposed pairs of substrate wafers for connection to external connector pins. Inter-level conductive interconnects (78) are embedded in one or more of the substrates for interconnecting the intra-level conductive strips of one substrate level with the intra-level conductive strips of a different level. In a preferred embodiment, four identical RAM chips are encapsulated and interconnected for multiplex operation in an over/under, dual in-line arrangement.

    摘要: Block redundancy is utilized to improve yield and lower die cost for an electrically programmable read only memory (EPROM). The EPROM is organized 8Kx8 with four primary memory blocks (12A, 12B, 12C, 12D) on each side of a central row decoder. Each block includes an array (M) of memory cells, column select (CS), solumn decode (CD), sense amp (SA), data buffer (DB) and other overhead circuitry. One block of redundant circuitry (12RB - 1) is also provided for each set of four blocks and includes a redundant memory matrix (RM), a redundant column decoder (RCD), a redundant column select (RCS), a redundant sense amp (RSA) and a redundant data buffer (RDB). Incorporated with each primary memory block is a multiplex logic circuit (MUX) which is independently programmable to selectively disconnect the associated primary memory block and substitute the redundant memory block, including the redundant column decoder, column select, sense amp and data buffer. Each multiplex logic circuit (26) includes a polysilicon fuse (30) which is permanently programmable from a closed to an open circuit condition by applying a high voltage to the external data bit terminal (P1) which corresponds with the detective memory block cells.

    摘要: A battery backup circuit for an MOS memory which has a multiplexed pin ((Alpha)WE) that functions to provide backup power to a memory cell array (50) upon loss of primary power Vcc. A voltage comparator (10) detects when the primary power Vcc becomes less than the backup voltage on the (Alpha)WE terminal. Upon detection of loss of primary power the memory cell array (50) is powered by a connection to the (Alpha)WE terminal. A primary power status signal ((Alpha)POK) indicates the status of the primary power and is driven to a state indicating insufficient circuit voltage for normal operation when Vcc drops below an acceptable limit or when there is inadequate substrate bias. The circuit of the present invention further generates an inhibit signal to prevent the operation of peripheral circuits (70) to write data into the memory cell array (50) upon detection of a failure of primary power. The inhibit signal is generated when primary power is lost or when the substrate bias is inadequate. A low-power auxiliary pump generator (92) provides a sufficient substrate bias to maintain the data pattern in the memory cell array (50) during the backup mode.
