Abstract:
Methods and systems that may employ adjustments to the latencies in the input circuitry to reduce the latency during initialization period and to prevent undesired effects from metastability are provided. Disclosed systems may employ adjustable delays during a signal training process to cause adjustments in the timing of the host that will reduce latencies during write cycles. Certain systems may further reduce latencies by employing input logic circuitry that produces a valid, consistent signal from the bidirectional connection, such as a gate, and preventing metastability in input circuitry altogether. Such circuitry allows bypassing of initialization periods to stabilize the input, and allows further reduction of the initialization.
