Claim Text:
1. A control device comprising: a first data strobe input terminal to be connected in common to data strobe terminals that are included respectively in first memory devices; a plurality of first sub-units each coupled to the first data strobe input terminal and each holding a data strobe delay value corresponding to an associated one of the first memory devices, and the data strobe delay values of the sub-units being independent from each other; a first data input terminal to be connected in common to data terminals that are included respectively in the first memory devices; and a first phase detector coupled to the first data input terminal and a common output terminal of the first sub-units; wherein the first phase detector is configured to detect a phase of a data strobe signal supplied via the first data strobe input terminal in response to a data signal supplied via the first data input terminal, so that each of the sub-units holds the data strobe delay value corresponding to the associated one of the first memory devices.
