The asynchronous data burst transfer circuit includes a data burst transfer oscillation
circuit which outputs n strobe signals of mutually different phases, plural parallel-serial
conversion circuits which convert n-bit parallel signals into serial signals, and
plural serial-parallel conversion circuits which convert serial signals into n-bit
parallel signals. The parallel-serial conversion circuits convert every n-bit parallel
signals of data read from a memory into serial signals based on the strobe signals,
and transfer the serial signals. The serial-parallel conversion circuits convert
the received serial signals into n-bit parallel signals based on the strobe signals,
thereby obtaining the parallel signals as the original data.
