    摘要: A memory device for reducing the number of data read lines needed in a memory device. Specifically, multiple helper flip-flops are used to prefetch data in a memory device. The helper flip-flops are configured to latch one or two of the data bits from a 4-bit prefetch in an alternating periodic fashion, thereby necessitating fewer data lines.

    摘要: Methods and apparatus are disclosed, such as those involving an interconnection layout for an integrated circuit (IC). One such layout includes a plurality of differential pairs of lines. Each differential pair has two lines including one or more parallel portions extending substantially parallel to each other. Each pair also includes a shield line. Each of the shield lines includes one or more parallel portions interposed between the parallel portions of one of the pairs of differential lines. One or more of the shield lines are electrically connected to a voltage reference, such as ground. This layout is believed to reduce or eliminate intra-pair coupling as well as inter-pair coupling.

    摘要: Selected transistors in a charge pump circuit have their associated well regions tied to a capacitor electrode. As a result, the body effect in these devices is reduced, and, consequently, the threshold voltage is reduced as well. With a lower threshold voltage, these transistors allow the charge pump to quickly generate a voltage higher than the positive power supply voltage or a negative substrate bias voltage. In addition, the metal-insulator-semiconductor (MIS) capacitors in the charge pump preferably have their source/drain regions tied to an associated well region, thereby shorting the source/drain/well region junction. Thus, parasitic capacitances associated with these MIS capacitors is significantly reduced, further increasing the speed of the charge pump circuit.

    摘要: For use in a semiconductor circuit device, a uniquely-arranged tri-state output buffer responds to a control signal generated in the semiconductor circuit device and a below-ground voltage level at an output terminal to prevent wasted drain current and substrate current, and reduce capacitance at the pull-up node driving the output terminal. The output buffer includes a power supply signal providing at least one voltage level with respect to common; an output terminal; a pull-up node; a pull-down node; a first circuit responding to the control signal by providing a first control voltage on the pull-up node; and a second circuit responding to the control signal by providing a second control voltage on the pull-down node. Further, the output buffer includes a pull-up transistor, responsive to the voltage on the pull-up node and coupled between the power supply signal and the output terminal; a pull-down transistor, responsive to the voltage on the pull-down node and coupled between common and the output terminal; a bias circuit, responsive to a voltage level on the output terminal being at a level substantially below common, arranged to bias the pull-up node downwardly and away from the voltage level provided by the power supply signal; and a disable circuit, responsive to the voltage level on the output terminal being at a level substantially below common, constructed and arranged to disable the circuit providing the control voltage on the pull-up node. The pull-up transistor provides a high-level signal at the output terminal, the pull-down transistor provides a low-level signal at the output terminal, and the bias circuit in combination with the disable circuit respond to the voltage level on the output terminal being at a level substantially below common by preventing current flow from the power supply signal to the output terminal.

    摘要: A voltage level translator is disclosed which translates a CMOS input signal into a CMOS output signal where the low voltage level of the output signal is equal to the high voltage level of the input signal. The voltage level translator is described in an integrated circuit such as memory circuits, including DRAMs. Specifically, the voltage level translator produces an output signal which can be used as a gate voltage on a pre-charge transistor for a booted circuit where the gate voltage need only drop to the high voltage level of the input signal to shut the transistor off. The voltage level translator described, therefore, reduces the time and power required to translate an input signal by limiting the voltage swing of the output signal.
