ABSTRACT:
A semiconductor device which performs a predetermined operation includes a timing-stabilization circuit which performs a timing adjustment with respect to an internal clock signal, and a current-consumption circuit which consumes a predetermined amount of a current so as to emulate conditions of such current consumption as would be observed during the predetermined operation of the semiconductor device. The semiconductor device further includes a start-up-period control circuit which makes the timing-stabilization circuit and the current-consumption circuit operate at a beginning of power supply so as to perform the timing adjustment under the conditions, and stops operations of the timing-stabilization circuit and the current-consumption circuit after completion of the timing adjustment.
