<p>PURPOSE:To provide a semiconductor IC(integrated circuit) which contains a reset signal and suppress the peak current produced in a reset mode in order to reduce noises on a power supply and a ground and also to suppress a latch-up state. CONSTITUTION:A 1st internal reset signal 6 that passes through a noise elimination circuit 5 is inputted to a delay circuit 7 of a delay time T0, and a 2nd internal reset signal 6a is outputted. Then a circuit that constructs a semiconductor IC 1a is divided into the logic circuit blocks 3a and 3b which have the same increment of current consumption measured in a reset mode. The signals 6 and 6a of different timings are supplied to both blocks 3a and 3b. Thus the increase of current can be halved in a reset mode.</p> |
