  • Device having an interface and method thereof
    Patent number: 7187598
    Abstract: A system device receives a first data signal and a first strobe signal from a dual-data-rate (DDR) memory. A first delay value representative of a delay to a predetermined phase location of the first strobe signal is determined. The first delay is adjusted based on a first offset value to generate a first adjusted delay value used to delay the first strobe signal. A first edge of a first pulse of the first delayed strobe signal is used to latch a first data value of the first data signal.
