    摘要: The present invention is a trigger device useful, for example, in triggering an SCR in an ESD protection circuit. Illustratively, an NMOS trigger device comprises a gate and heavily doped P and N regions in a P-well on opposite sides of the gate. A first N type source/drain extension and a first P-type pocket region extend from the P region toward the N region with the pocket region located under the source/drain extension and extending under the gate. A second N-type source/drain extension and a second P-type pocket region extend from the N region toward the P region with the pocket region located under the source/drain extension and extending under the gate. Preferably, the gate itself is heavily doped so that one half of the gate on the side adjacent the heavily doped P region is also heavily doped with dopants of P-type conductivity and the other half of the gate on the side adjacent the heavily doped N region is also heavily doped with dopants of N-type conductivity. Doping the gate increases the threshold voltage by about one Volt due to an increase in the work function on the source side of the gate.

    摘要: A programmable logic device (PLD) includes mechanisms for adjusting or setting the body bias of one or more transistors. The PLD includes a body-bias generator. The body-bias generator is configured to set a body bias of one or more transistors within the programmable logic device. More specifically, the body-bias generator sets the body bias of the transistor(s) so as to trade off performance and power consumption of the transistor(s).

    摘要: A configuration memory cell (“CRAM”) for a field programmable gate array (“FPGA”) integrated circuit (“IC”) device is given increased resistance to single event upset (“SEU”). A portion of the gate structure of the input node of the CRAM is increased in size relative to the nominal size of the remainder of the gate structure. Part of the enlarged gate structure is located capacitively adjacent to an N-well region of the IC, and another part is located capacitively adjacent to a P-well region of the IC. This arrangement gives the input node increased capacitance to resist SEU, regardless of the logical level of the input node. The invention is also applicable to any node of any type of memory cell for which increased resistance to SEU is desired.

    摘要: Methods and apparatus are provided for harnessing the effects of process variations in a semiconductor device. In one example, implementing an electronic design based on collected performance parameters is provided. In general, a core is segmented into multiple core regions. A performance parameter can be collected from each of the core regions. The performance parameter can be collected with a performance measuring mechanism associated with the core region. The performance parameter can be correlated to the performance requirements of an electronic device portion, and the electronic design portion can be implemented in a core region that has a performance parameter matched to the needs of the electronic design portion. In this way, process variation effects are harnessed by optimizing the implementation of the electronic design in regions of the semiconductor device best suited the needs of each electronic design portion. Therefore, performance/power optimization of the semiconductor device can be realized.
