Abstract:
A semiconductor integrated circuit device related to an embodiment of the present invention includes an address register which includes an internal selection circuit connected with a control circuit, a signal generation instruction circuit which instructs the control circuit so that a predetermined internal control signal is generated, a latch circuit, a plurality of which are arranged corresponding to a number of bits of test parameter data, the latch circuit latching test result data which is provided from the data program/read circuit and outputting the test result data to the selection circuit and externally, the control circuit generating an internal control signal which activates the selection circuit at a timing at which a fixed value data of the test parameter data is changed, and the selection circuit controlling a test so that a fixed value data of the test parameter data is changed.
