摘要： A method transfers read data from a flash memory to a controller synchronously with respect to a data strobe signal during a read data transfer period. During an initial control period of the read data transfer period, the cycle of the data strobe signal is expanded such that a pulse width of the resulting cycle-controlled data strobe signal is greater than a pulse width of the data strobe signal.
