ABSTRACT:
A memory controller. A first counter is triggered by rising edges of a data strobe signal and generates a first count value. A second counter is triggered by falling edges of the data strobe signal and generates a second count value. A third counter is triggered by rising edges of an internal clock and generates a third count value. A first buffer uses the first count value as a write address for sequential storage of the data corresponding to the rising edges of the data strobe signal, and sequential outputs the data corresponding to the third count value after a first predetermined period. A second buffer uses the second count value as the write address for sequential storage of the data corresponding to the falling edges of the data strobe signal, and sequential outputs the data corresponding to the third count value after the first predetermined period.
