Abstract
A control device that comprises a first data strobe input terminal to be connected in common to data strobe terminals that are included respectively in first memory devices, and 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.
Claims16
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;
- and
- 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 control device, comprising:
- a data strobe input terminal connected in common to data strobe terminals of a plurality of memory devices;
- and
- a data input unit that holds a plurality of data strobe delay values, the data strobe delay values being independent from each other and corresponding to each of the memory devices, wherein
- the data input unit adjusts a phase of a data strobe signal, supplied from one of the memory devices, depending on a data strobe delay value that is selected from among the data strobe delay values and corresponds to the one of the memory device;
- the data input unit latching a data signal received from the one of the memory device via the data strobe input terminal depending on the adjusted data strobe signal.
