  • Patent number: 6081132
    Abstract: A high voltage drive output buffer for low voltage integrated circuits comprising a pullup pFET; a driver pFET having a source connected to the drain of the pullup pFET, and having a gate connected to a biasing circuit; a driver nFET having a drain connected to the drain of the driver pFET, and having a gate connected so as to be biased; and a pulldown nFET having a drain connected to the source of the driver nFET; wherein the pullup pFET and pulldown nFET are coupled to switch in complementary fashion in response to an input voltage; and wherein the biasing circuit comprises an nFET having a drain connected to the gate of the driver pFET and coupled to the input node so as to switch ON for a transitory period when the pullup pFET switches from OFF to ON.

  • Patent number: 6069512
    Abstract: A half latch for latching a voltage at a domino gate output with reduced crossbar current duty cycle, comprising a CMOS inverter with input connected to the domino gate output, a first pMOSFET having a gate and drain connected to ground and having a source coupled to the source of the nMOSFET of the CMOS inverter to prevent the source voltage of the nMOSFET from approaching ground, and a second pMOSFET having a gate connected to the output of the CMOS inverter and having a drain connected to the input of the CMOS inverter.

  • Patent number: 6058403
    Abstract: A broken stack domino priority encoder to provide a set of voltages to uniquely identify the position of a leading one or leading zero in a binary word, the domino priority encoder comprising a by-pass stack of nMOSFETs and a broken stack of nMOSFETs to discharge various nodes. The stack depth of nMOSFETs between each node and ground is minimized in order to maximize switching speed of the priority encoder.

  • Patent number: 6003121
    Abstract: A method for BIOS code for detecting and grouping memory devices connected to one or more memory channels, comprising reading characteristics of a memory device and if the characteristics have not been previously read, then programming device ID and group ID registers based upon a device counter and a group counter, respectively. The method further includes steps for properly incrementing the device and group counters so that additional memory devices on the channel may be read and grouped.

  • Patent number: 5986473
    Abstract: A driver to provide low voltage swings on a bus with fast switching times, the driver comprising two pairs of pullup and pulldown nMOSFETs, each pair operated in complementary fashion to each other, each pair with a high voltage rail at a smaller voltage than the data input logic HIGH voltage, and where each substrate of the nMOSFETs are biased so as to reduce their threshold voltages.
