Abstract: A control circuit provided in a semiconductor device receives an input data signal during a selection period in which a selection signal has a predetermined level in synchronization with a clock signal and performs a corresponding operation corresponding to the input data signal during the selection period or after the selection period. The control circuit holds an error flag indicating whether a specific error has occurred, outputs, during a part of the selection period, a response signal corresponding to the input data signal from a data output terminal and outputs, during another part of the selection period, an error flag signal corresponding to the value of the error flag from the data output terminal.

Abstract: A semiconductor device comprises: an upper control input terminal; a lower control input terminal; a power supply terminal; a control logic unit; a reference power supply circuit configured to receive supply of the power supply voltage and to allow generation of a reference power supply voltage to be supplied to the control logic unit; and a switch circuit including switches provided for the upper control input signal and the lower control input signal respectively and switched between on and off in response to logic levels of the upper control input signal and the lower control input signal respectively. The reference power supply circuit is configured to be activated on the basis of a combination of the logic levels of the upper control input signal and the lower control input signal.
