Data paths using a first signal to capture data and a second signal to output data and methods for providing data

摘要

Data paths, memories, and methods for providing data from memory are disclosed. An example read data path includes a delay path, and a clocked data register. The data path has a data propagation delay and is configured to receive data and propagate the data therethrough. The delay path is configured to receive a clock signal and provide a delayed clock signal having a delay relative to the clock signal that models the data propagation delay. The clocked data register is configured to clock in data responsive at least in part to the delayed clock signal. The clocked data register is further configured to clock out data responsive at least in part to the clock signal.

1. An apparatus, comprising:
a data register configured to receive interleaved data from a data path and to provide the interleaved data, wherein the data register is configured to provide the interleaved data based on a clock signal and further configured to receive the interleaved data based on a delayed clock signal, wherein a delay of the delayed clock signal is approximately the same as a delay of the data path.
