Abstract
In order to easily perform a timing test on a memory interface included in a semiconductor device so as to satisfy a restriction on latency, the present invention provides a semiconductor device with the memory interface including: a clock output terminal that outputs a clock signal associated with an operation of a memory connected to the memory interface; a command terminal that outputs a command signal associated with control of a state of the memory; a data terminal that exchanges a data signal with the memory; and a data strobe terminal that exchanges a data strobe signal for establishing the data signal. This semiconductor device includes a testing terminal that outputs in advance a signal for starting a test on the memory interface apart from the command signal.
