    摘要: A voltage boosting circuit which derives an output voltage than is substantially twice the magnitude of a supply voltage applied thereto. The voltage boosting circuit consists of complementary acting boost circuits each having a pair of switches (42A, 52A; 42B, 52B) connected between an input of the voltage boosting circuit, at which is applied the supply voltage, and an output at which the output voltage is produced. Boost capacitors (48A, 48B) are connected between the respective switches of the complementary boost circuits and the switches of the these circuits are opened and closed out of phase with respect to each other in response to clocking signals being applied thereto such that a boosted output voltage is produced during each half cycle of the clocking signals.

    摘要: Bipolar memory arrays having lower quiescent leakage and higher switching speed are constructed by using coupled SCRs formed from vertical PNP and NPN devices. Buried collectors for the PNP and NPN devices are provided within the same isolation tub. A P type plug is used to connect the P collector of the PNP to the P base of the NPN in a region where the P base and P collector overlap. A single N epi-region serves as the base of the PNP and the collector of the NPN. The P plug is located within this N epi-region but part of the N epi-region adjacent to or around the P plug is left so that internal connection of the PNP base and NPN collector is not cut off by the P plug. The structure is particularly suited for use in large memory arrays. The method of fabrication is also described.

    摘要: A voltage level translator circuit converts an input signal referenced between first and second operating potentials to an output signal referenced between second and third operating potentials. The input signal is level shifted through cascoded transistors and latched by series inverters to drive upper cascoded transistors in the output stage. The input signal is delayed before driving lower cascoded transistors in the output stage. The output stage transistors are cascoded in a similar manner as the level shifting section. The logic state of the input signal determines whether the upper cascoded transistors or the lower cascoded transistors in the output stage are activated to set the logic state of the output signal of the voltage level translator circuit. Additional cascoded transistors may be stacked to extend the range of voltage translation. The voltage level translator circuit is applicable to sub-micron technology.

    摘要: A bipolar complementary metal oxide semiconductor (BICMOS) sense circuit for sensing data on read data lines during a read cycle of a memory comprises a load portion and a sense amplifier portion. In one form, the load portion couples true and complement read data lines to a first voltage in response to a start of a read cycle. When the true and complement read data lines exceed a predetermined voltage, the sense amplifier is enabled. The load portion becomes inactive when the voltage on the read data lines reaches approximately the first voltage. Then a selected memory cell provides a differential voltage on a bit line pair, which is coupled to the read data lines, indicating the contents of the selected memory cell. The sense amplifier provides a differential current onto a corresponding read global data line pair in response to the differential voltage. At the termination of the read cycle, the load portion becomes active again and couples the read data lines to a second voltage to disable the sense amplifier. The predetermined voltage is between the first voltage and the second voltage. The circuit increases the speed of the sensing function over a CMOS design, while keeping power consumption to a minimum. In another form, the sense circuit generates a read sense voltage that is substantially independent of non-tracking process variations between P-channel and N-channel field-effect transistors.
