    • A sum decoder is disclosed including multiple sum predecoders, a carry generator, and multiple rotate logic units. Each sum predecoder receives multiple bit pairs of non-overlapping segments of a first and second address signal, and produces an input signal dependent upon the bit pairs. The carry generator receives a lower-ordered portion of the first and second address signals, and generates multiple carry signals each corresponding to a different one of the sum predecoders. Each rotate logic unit receives the input signal produced by a corresponding sum predecoders and a corresponding one of the carry signals, rotates the bits of the input signal dependent upon the carry signal, and produces either the input signal or the rotated input signal as an output signal. A memory is described including the sum decoder, a final decode block, and a data array. The final decode block performs logical operations on the output signals of the sum decoder to produce selection signals. Each of the selection signals activates a word line of the data array. A method is disclosed for producing signals for accessing a memory. Highest ordered portions of the first and second address signals are divided into multiple non-overlapping segments. An input signal (i.e., an I term) is generated for each of the segments, as is a carry signal. For each of the segments, when the corresponding carry signal is set, the corresponding I term is rotated one bit position. The I terms are produced as the signals.

    • A system and method with a self-reset circuit for synchronizing an input data path with a timing control path. The self-resetting circuit includes a normal-mode input detect circuit which detects an arrival of data from the input data path into the self-reset circuit and generates a normal-mode control signal in response thereto. The self-resetting circuit also includes a delay-mode input detect circuit for detecting the arrival of the data from the input data path and which generates a delay-mode control signal in response thereto. A toggle circuit is provided for disabling the normal-mode input detect circuit while simultaneously enabling the delay-mode input detect circuit. In response to the toggle circuit disabling the normal-mode input detect circuit, the delay-mode control signal propagates through a delay gate, such that said delay-mode control signal synchronizes said timing control path with respect to said data input path.

    • A latching dynamic logic structure is disclosed including a static logic interface, a dynamic logic gate, and a static latch. The static logic interface receives a data signal, a select signal, and a clock signal, and produces a first intermediate signal such that when the select signal is active, the first intermediate signal is dependent upon the data signal for a period of time following a clock signal transition. The dynamic logic gate discharges a dynamic node following the clock signal transition dependent upon the first intermediate signal. The static latch produces an output signal assuming one of two logic levels following the clock signal transition, and assuming the other logic level in the event the dynamic node is discharged. A scan-testing-enabled version of the latching dynamic logic structure is described, as is an integrated circuit including the latching dynamic logic structure.

    • A local clock signal generation system is disclosed including multiple local clock buffers each receiving a global clock signal and producing a version of one or more local clock signals derived from the global clock signal. Each local clock buffer includes an input section and an output section. The input sections are substantially identical such that timing differences between the versions of the one or more local clock signals are reduced. An electronic circuit is described including the local clock signal generation system and a latch (e.g., a master latch of a flip-flop). A local clock buffer produces a gating signal and a local clock signal received by the latch. When the gating signal is a certain logic value, the local clock signal is a steady logic value, and the latch produces an input data signal as an output signal. An integrated circuit including the electronic circuit is disclosed.
