摘要： A method and apparatus for random-access scan of a network 990 of dynamic logic or N-NARY logic that includes sequentially clocked precharge logic gates and one or more scan gates (900) driven by multiple overlapping clock signals generated from a clock generation circuit (904) coupled to a clock spine (902). Each clocked precharge logic gate and each scan gate include a logic tree (502) with one or more evaluate nodes, a precharge circuit (32), an evaluate circuit (36), and one or more output buffers (34). Each scan gate further includes a scan circuit (806) that accepts scan control signals (406, 408, 410, 824, and 826) and couples to one or more scan registers (416) in a RAM-like architecture.

The logic circuit additionally comprises a 1 of Q second input signal that comprises a plurality of wires wherein each wire of said plurality of wires has equal capacitive loading. A logic tree circuit couples to the first input signal and the second input signal. The logic tree circuit generates a result for a 1 of R output signal, which couples to the logic tree circuit. The 1 of R output signal comprises a plurality of wires wherein each wire of said plurality of wires has equal capacitive loading. The power consumption of the logic circuit is independent of the value of the first signal or the second signal, which results in the logic circuit having constant power consumption. Additionally, the logic circuit has a consistent current demand. The present invention provides that exactly one wire of the plurality of wires of the output signal is charged and discharged every clock cycle.

A scan control circuit generates scan control signals and scan timing signals which operate to capture the state of the output buffers of the scan gate and provide that state to one or more scan registers. Scan control signals and scan timing signals also operate to force the output buffers of the scan gate to a preselected level, which then propagates through the network to create an output state on the next scan gate in the network, which can then be read and compared to an expected output state given the output state of the previous scan gate.

摘要： 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.
摘要翻译：具有感测触发器的存储器件，其在耦合到可用时接收地址，并且当感测触发器接收到地址时，将感测触发信号置于感测触发器。存储器件还具有N / N或N输入逻辑门，其提供额外的保证，即当解码地址时不超过一个字线被断言。存储器件还具有N输出或1-N输出驱动器逻辑门，其提供直接用于提供给另一（N-Nary）1-N逻辑门的输出信号。
