Abstract
According to the system of the present invention, data (DQ) signals are outputted/received between a controllerand a memorybased on a data strobe signal sent out from the controller. The data strobe signal is independently and completely separated from a clock signal. The data strobe signal has a frequency different from a clock signal. Therefore, the memoryis not required to generate a read data strobe signal from the clock signal nor to send the read data strobe signal in synchronization with the clock signal.
