Patent attributes
An apparatus comprising an open loop circuit and a delay circuit. The open loop circuit may be configured to generate an in-phase clock signal by performing a phase alignment in response to (i) a clean version of a system clock and (ii) a delayed version of a strobe signal. The delay circuit may be configured to (i) generate the delayed version of the strobe signal in response to (a) the strobe signal received from a memory interface and (b) a delay amount received from a calibration circuit and (ii) adjust a delay of transferring a data signal through the apparatus in response to (a) the delay amount and (b) the in-phase clock signal. The data signal may be received from the memory interface. The delay of transferring the data signal may be implemented to keep a latency of a data transfer within a pre-defined range.
