Abstract
The data access apparatus comprises a phase locked loop (PLL) and a data receiving circuit. The PLL provides a plurality of internal clocks and selecting a strobe clock from the plurality of internal clocks according to a phase selection signal. The data receiving circuit comprises a latching module, for latching of the data signal according to trigger of the strobe clock and a calibrating circuit, for generating the phase selection signal for matching the data with a predetermined data according to the plurality of internal clocks in a training mode and finally determining the phase selection signal corresponding to a preferred clock used in a normal mode.
