摘要: A current driver circuit (10) sources current to an output node (N4) in response to an input signal (VI) being a logic high. The current driver circuit (10) utilizes a current source (16) which sinks current from the output node (N4) in response to the input signal (VI) switching from a logic high to a logic low. The current source (16) is deactivated for a predetermined time delay after the input signal (Vi) switches from a logic high to a logic low.

摘要: In integrated circuits which include both ECL and CMOS circuits, there is an ECL to CMOS translator which converts ECL logic levels to CMOS logic levels. To convert from ECL to CMOS levels, the ECL logic high is coupled to the base of an NPN transistor which provides a CMOS logic low. The ECL logic low is prevented from being coupled to the base of the NPN transistor. The CMOS logic high is obtained by an analogous second circuit which is responsive to a complementary ECL signal the output of which is coupled to a P channel transistor. The P channel transistor either provides the CMOS logic high output or is non-conductive.

摘要: A memory has an address buffer which receives a row address and a column address and outputs these buffered address signals to a predecoder. A row decoder and column decoder use predecoded signals provided by the predecoder to select a row and a column from a main array. A redundant row is provided to replace a defective row from the main array. A programmable redundant decoder is programmable to select the redundant row in response to the predecoder signals which select the defective row.

摘要: A dynamic random access memory has data line pair which receives data from a selected pair of bit lines. Coupled to the data line pair is a secondary amplifier for amplifying the data provided to the data line pair from the bit line pair. The secondary amplifier has a maximum gain when the inputs are at a voltage intermediate a power supply voltage. Prior to the pair of bit lines being coupled to the data line pair, the data lines are biased to the intermediate voltage which is in the range of maximum gain of the secondary amplifier so that the secondary amplifier will operate at maximum gain which results in increased speed of operation of the dynamic random access memory.

摘要: A double-rate memory has an array of single word line memory cells arranged in rows and columns. The single word line memory cells provide and store data via a first port. Addressing and control circuitry is coupled to the array of single word line memory cells. The addressing and control circuitry receives an address enable signal to initiate an access of the array whereby an address is received, decoded, and corresponding data retrieved or stored. Edge detection circuitry receives a memory clock and provides the address enable signal upon each rising edge and each falling edge of the memory clock to perform two memory operations in a single cycle of the memory clock. A memory operation includes addressing the memory and storing data in the memory or retrieving and latching data from the memory. In another form a double-rate dual port memory permits two independent read/write memory accesses in a single memory cycle.

摘要: An output buffer (200) having a protection circuit (228, 230, 232) which adjusts control of an output drive circuit (224,226) in response to external voltages on the output pin (202). When the output pin is in a tri-state condition and receives an external voltage which is outside a predetermined voltage range, the protection circuit adjusts the voltage on the control gate of a transistor (224) in the output drive circuit. The protection circuit maintains the voltage across the transistor within the tolerance of the transistor. In one embodiment, the output drive circuit has pullup (204) and pulldown (206) portions. The output buffer provides a high voltage output driver having low voltage devices.

摘要: A data value is passed from a bus (50) to a receiver (40) without a propagation delay. A data latch (10) stores the data value while the data value is being generated by the bus (50). The data latch (10) then holds the data value and provides the data value to the receiver (40) after the data value is no longer present on the bus (50). The data latch (10) has a data storage circuit (11), a diode clamping circuit (12), and a current sourcing circuit (13). The data value is stored by the data storage circuit (11) by a feed-back loop circuit.

摘要: A memory (110) having sections of memory cells used ATD to generate the required timing signals, includes ATD generators (189), first summation circuits (180-183), and local summation circuits 185-187. An ATD pulse is generated by the ATD generators (189) when an address signal transitions from one logic state to another. The outputs of the ATD generators (189) are wired-OR connected to input terminals of first summation circuits (180-183). A first summation signal is provided by the first summation circuits (180-183) to each of the local summation circuits (185-187). The local summation circuits (185-187) are positioned in the vicinity of the areas where the timing signals are used. Localized generation of the ATD signals prevents the timing signals for being excessively skewed from each other in different portions of the memory (110).

摘要: A memory which contains a global data line pair and a plurality of loads for the global data line pair distributed thereon. The global data lines run the length of the memory, and are connected to a set of arrays distributed along the global data lines, of which each array provides a voltage on the global data lines when selected. The first load is located above the first array and the last is located below the last array. Other global data line loads are placed between consecutive arrays. In a read mode of operation a pair of loads associated with each array is enabled when a corresponding array is selected. Placement of the loads in this manner decreases an access time considerably.
