    摘要: A pumpdown circuit uses voltage sensing to bring a low node to a potential of V.sub.SS +V.sub.T by first grounding the node and then floating the node to the V.sub.SS +V.sub.T potential. When a sensing node is at the V.sub.SS +V.sub.T potential, the sensing node is maintained at a level above ground by leakage current through a pump-up circuit. Biasing the digit and digit* lines to a potential V.sub.T above ground reduces current (amperage) requirement, because the digit and digit* lines do not have to be discharged completely to ground. The momentary discharge of the sense amp node to ground allows the sense amp to behave like a conventional sense amp during initial sensing, thereby allowing a minimum digit/digit* sensing potential to approximate ground plus V.sub.T.

    摘要: A voltage sensing circuit is used to rapidly pull up a high potential node of a reference array to a value of a high potential source reduced by a threshold voltage (V.sub.CC -V.sub.T). During an enable cycle, the high potential node is precharged to a potential of V.sub.CC -V.sub.T, which turns on a transistor gated to the V.sub.CC potential. This pulls the high potential node as rapidly as possible to a high level in order to speed up the sensing process. A potential maintenance circuit provides sufficient current from the high potential source to maintain a desired potential at the high potential node.

    摘要: A memory array (e.g., DRAM) is provided with a potential maintenance circuit which provides sufficient current to maintain a high potential node of the memory array at a predetermined potential. The potential maintenance circuit is gated ON after receipt of a clock signal and gated OFF at the predetermined potential. This permits the high voltage node to be maintained, while reducing current requirements. The invention is particularly useful when used in conjunction with a circuit which rapidly pulls up the high node to a value of V.sub.CC -V.sub.T (where VT is a threshold voltage of a transistor).

    摘要: An integrated cirucuit is provided with a depletion mode filter capacitor, which reduces voltage spiking, while at the same time avoiding latchup problems caused by the capacitor. The depletion mode capacitor has a barrier layer which is doped to an opposite conductivity type as the integrated circuit's substrate, achieved by doping to provide an opposite difference from four valence electrons as the substrate. The barrier is formed as a part of a CMOS process, in a manner which avoids additional process steps. The capacitor is formed with one node connected to ground or substrate, and the other node directly to a power bus. The capacitor is located on open space available on the whole siliocn chip (memory as well as logic chip), particularly directly underneath the metal power bus to achieve an on-chip power bus decoupling capacitor wth capacitance in excess of 0.001 .mu.F.

    摘要: I/O lines on a CMOS circuit are precharged to preferred voltage levels in order to avoid latch up. The precharging is achieved by using N channel transistors to provide a precharge which is at a threshold voltage (V.sub.T) below bias voltage V.sub.CC, or (V.sub.CC -V.sub.T). This results in a lower forward bias when V.sub.CC bumps down after the I/O lines are floated. By lowering the precharge voltage by a level corresponding to a threshold voltage (V.sub.T), the allowed range of power supply voltage bumping is increased by this amount. This eliminmates the destructive effect of a negative bump of V.sub.BE, which would have presented a diode forward bias condition. Instead, the power supply may bump to (V.sub.BE +V.sub.T).
