    摘要: A method includes providing power to on-die combinatorial circuitry of an integrated circuit (IC) from an external power supply regulator during an active mode of the IC. A state of the on-die combinatorial circuitry of the IC is moved into on-die storage of the IC. Power to the on-die combinational circuitry is disabled during a low power mode of the IC by disrupting power supplied from the external power supply regulator to the IC. A power feedback signal from an internal portion of the IC is provided to the external power supply regulator.

    摘要: The present invention provides a PLA architecture where the AND plane is implemented with NAND logic. The OR plane may be implemented with various logic, but in one embodiment, the OR plane is implemented with NOR logic. The AND plane may have multiple sequential stages providing hierarchical NAND logic. The NAND logic may be broken into a hierarchy of NAND logic blocks. Each NAND logic block may include one or more series-connected NAND transistor stacks. Each transistor in the transistor stack may receive an input signal representing the product of a PLA clock signal and either a direct PLA input or the complement thereof. As such, the PLA clock is inherently integrated with the input signals that drive the various transistors of the NAND transistor stacks.

    摘要: A method and apparatus for employing a light shield to modulate pixel color responsivity. The improved pixel includes a substrate having a photodiode with a light receiving area. A color filter array material of a first color is disposed above the substrate. The pixel has a first relative responsivity. A light shield is disposed above the substrate to modulate the pixel color responsivity. The light shield forms an aperture whose area is substantially equal to the light receiving area adjusted by a reduction factor. The reduction factor is the result of an arithmetic operation between the first relative responsivity and a second relative responsivity, associated with a second pixel of a second color.

    摘要: In one embodiment, an array of content addressable memory (CAM) cells include a first plurality of CAM cells and a second plurality of CAM cells. The second plurality of CAM cells has a width sufficient to address a height of the array. A first plurality of CAM drivers are coupled to the array to drive the first plurality of CAM cells. The first plurality of CAM drivers prevent the first plurality of CAM cells from participating in a match when the array is in a test mode.
