A mode decode/latch circuit decodes an input signal based on a latch timing signal to output a test mode signal to a test execution circuit. Test mode signal line includes a high-resistance portion extending from the mode decode/latch circuit toward the vicinity of the test execution circuit and a low-resistance portion connecting together the distal end of the high-resistance portion and the input of the test execution circuit. A latch circuit for latching the test mode signal based on the latch timing signal is inserted in the low-resistance portion.
