Provided is a delay adjustment device that contributes to downsizing the circuit that adjusts a flight time. The delay adjustment device is connected to a memory, and adjusts a timing to retrieve data with a data signal and a data strobe signal output from the memory. The delay adjustment device includes a data retrieve unit that receives the data signal and the data strobe signal, and outputs a data value of the data signal in accordance with the data strobe signal; and a control unit that issues a read command to the memory, calculates a flight time, and controls a valid period of the data strobe signal based on the flight time. |
