Abstract
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.
Claims20
An apparatus comprising:
- a clock path configured to delay a clock signal approximately a same amount as a data signal is delayed in a data path;
- and
- a data register coupled to the clock path and the data path and configured to capture data based on the delayed clock signal and provide the data based on the clock signal.
A method comprising:
- propagating data through a data path to a data register;
- delaying a clock signal by a delay that models a propagation delay of the data path;
- capturing data by the data register based on the delayed the clock signal;
- and
- providing the data by the data register based on the clock signal.
An apparatus comprising:
- a data path configured to receive data and propagate the data, the data path having a data path propagation delay and the data path comprising a multiplexer controlled by a control signal;
- a clock path configured to receive a clock signal and delay the clock signal an amount of delay substantially equal to the data path propagation delay;
- and
- a data register configured to receive the data in response to the delayed clock signal and provide the data in response to the clock signal.
