DETERMINATION SUPPORT APPARATUS, DETERMINING APPARATUS, MEMORY CONTROLLER, SYSTEM, AND DETERMINATION METHOD

摘要

A determination support apparatus includes a detecting unit that detects a phase difference between a first clock signal and a second clock signal that is identical in frequency to the first clock signal; a control unit that controls delay of at least one among the first clock signal and the second clock signal such that the detected phase difference becomes less than a given amount; and an acquiring unit that acquires values of a given clock signal among the first clock signal and the second clock signal, among which at least one has been subject to delay control by the control unit, wherein the acquiring unit acquires the values of the given clock signal at a timing that is based on a clock signal that is other than the given clock signal and among the first clock signal and the second clock signal.
