Abstract
The present disclosure discloses a memory access interface device. A clock generation circuit generates a reference clock signal. A fake data strobe signal generation circuit receives the reference clock signal and delays a read enable signal from a memory access controller to enable an output of the reference clock signal to generate a fake data strobe signal. A real data strobe signal generation circuit receives a data strobe signal from a memory device and delays the read enable signal to enable an output of the data strobe signal to generate a real data strobe signal. A data reading circuit samples a data signal from the memory device according to a sampling signal to generate a read data signal to the memory access controller. A selection circuit selects the fake and the real data strobe signals as the sampling signal respectively under a single and a double data rate modes.
