For example, in accordance with an embodiment of the present invention, an integrated circuit includes an address register that receives a reset signal, a clock signal, and an address signal and provides a registered address signal. The registered address signal provides at least a true and a complement signal, with the true and complement signal set to approximately the same logical value upon assertion of the reset signal. An address pre-decoder, coupled to the address register, at least partially decodes the registered address signal to provide a pre-decoded output signal. A wordline driver, coupled to the address pre-decoder, receives a wordline enable signal and the pre-decoded output signal and provides a wordline signal based on the pre-decoded output signal upon assertion of the wordline enable signal.

Each control signal is generated by a set-reset latch that receives its set and reset signals from different pulse generators operating based on different delayed clock signals from the clock-delay circuitry. In one implementation, the clock-delay circuitry has a partitioned delay block in which different sub-blocks provide different delay functionality to provide the clock-delay circuitry with programmable flexibility.

Abstract: A clock multiplexer selects between two asynchronous clock signal inputs to produce a clock signal output such that the clock signal input corresponding to the clock signal output may be denoted as the current clock signal and the remaining clock signal input may be denoted as the selected clock signal. After detecting an edge of a specified type in the current clock signal, the clock multiplexer holds the clock signal output either high or low according to the specified type of clock edge being detected. After detecting an edge of the specified type in the selected clock signal, the clock signal output is released and the selected clock signal allowed to pass.
