Patent ID: 8289789

Claim:
A semiconductor device comprising: a first data input/output terminal; a second data input/output terminal; a first strobe terminal that is provided to correspond to the first data input/output terminal and to which a first strobe signal is supplied; a second strobe terminal that is provided to correspond to the second data input/output terminal and to which a second strobe signal is supplied; and a control circuit that performs, when a first word structure is designated, control such that input and output of data is performed from the first data input/output terminal and from the second data input/output terminal in response to the first strobe signal and the second strobe signal, performs, when a second word structure is designated and when a first control signal is supplied, control such that input and output of data is performed from the first data input/output terminal in response to the first strobe signal, and performs, when the second word structure is designated and when a second control signal is supplied, control such that input and output of data is performed from the second data input/output terminal in response to the second strobe signal.
