A method and apparatus for fine tuning a memory interface includes
receiver operative to receive an input signal. The method and apparatus
includes a clock counter operative to calculate a time value based upon
the timed sequence determined by the reception of the input signal. The
method and apparatus further includes a comparator coupled to receive an
input strength indicator signal from the receiver and operative to
generate a comparative strength signal based on the comparison of the
input signal strength indicator signal and a reference strength signal.
Furthermore, the method and apparatus includes a tuner coupled to the
clock counter so the tuner receives the time value from the counter, and
coupled to the comparator to receive the comparative strength signal from
the comparator, whereupon the tuner then generates a tuning signal
utilized for an iterative tuning process to fine tune a memory interface.
