  • Method and apparatus for fine tuning a memory interface
    Patent number: 7337346
    Abstract: 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.
