Abstract:
A controller, includes a plurality of external terminals configured to supply a command and an address to a semiconductor memory device, communicate a data with the semiconductor memory device, and communicate a strobe signal related to the data, at least one external terminal among the plurality of external terminals being configured to be capable of supplying an information specifying a length of a preamble of the strobe signal before the semiconductor memory device communicates the data.
