  • Patent number: 6154120
    Abstract: The present invention is an N-nary equality comparator that receives as inputs two 32-bit 1-of-4 operands. The equality comparator generates an "equal" indicator if the values of the two operands are equal. The equality comparator generates a "not equal" indicator if the values of the two operands are not equal.

  • Patent number: 6118716
    Abstract: A memory device having a sense trigger coupled to receive an address when available, and to assert a sense trigger signal to the sense trigger when the sense trigger receives the address. The memory device also has an N-nary, or 1-of-N, input logic gate that provides additional assurance that no more than one word line is asserted when an address is decoded. The memory device also has an N-nary, or 1-of-N, output driver logic gate that provides an output signal directly useful for providing to another (N-nary) 1-of-N logic gate.

  • Patent number: 6069497
    Abstract: The present invention is a method and apparatus for a N-nary logic circuit that comprises a logic tree circuit that couples to a first set of input logic paths, a second set of input logic paths, and a set of output logic paths, which all use 1 of N signals where one and only one of the N logic paths is active during an evaluation cycle. The preferred embodiment of the present invention uses 1 of 4 signals, while other embodiments of present invention include 1 of 2 signals, 1 of 3 signals, 1 of 8 encoding, and the general embodiment of the 1 of N signals. The logic tree circuit evaluates a given function that includes, for example, an AND/NAND function, an OR/NOR function, or an XOR/Equivalence function. The logic tree circuit uses a single, shared logic tree with multiple evaluation paths for evaluating the function of the logic circuit.
