Abstract:
Memory devices may provide a communication interface that is configured to receive control signals, and/or address signals from user circuitry, such as a processor. The memory device may receive and process signals employing different signal paths that may have different latencies, leading to clock skews. Embodiments discussed herein the application are related to interface circuitry that may decrease certain response times of the memory device by adding delays that minimize the clock skews. For example, a delay in a control path, such as a chip select path, may allow reduction in a delay of an address path, and leading to a decrease of the access time of the memory device. Embodiments also disclose how training modes may be employed to further adjust the delays in the control and/or address paths to decrease access times during regular operation.
