Improved integrated circuits, memory devices, circuitry, and data methods
are described that facilitate the adjustment and reconstruction of signal
timing of devices by providing for an interface having inputs and/or
outputs that are adjustably delayed. This allows embodiments of the
present invention to sense the signal delay and utilize adjustable input
or output delays to correct the signal timing relationships such that
correctly timed communication signals are received by the internal
circuitry of the device. In one embodiment of the present invention, a
register is utilized to adjust the timing delay of individual input
and/or output signals for the device. This increases the robustness of
the device and its resistance to communication or data corruption,
allowing larger ranges of environmental conditions and input capacitances
of systems or communication busses to be tolerated.
