Abstract
A timing adjustment circuit includes at least one data line; a phase synchronization circuit that includes a plurality of oscillation delay elements which oscillate an oscillation signal, and that is configured to oscillate the oscillation signal by synchronizing a phase of a feedback clock with a phase of a reference clock; at least one delay circuit that includes a delay element which is disposed on the data line and which is equivalent to one of the plurality of oscillation delay elements, and that is configured to delay data which is to be transmitted on the data line; and a delay adjustment unit configured to adjust an amount of delay of the delay element of the delay circuit in accordance with a signal associated with oscillation of the phase synchronization circuit.
