PURPOSE: A column repair circuit is provided, which can reduce current consumption by using a latch type X-fuse block and a dynamic type Y-fuse block without a transfer control circuit to transfer information of an X-fuse set to a Y-fuse set. CONSTITUTION: A latch type X-fuse block(500) includes a latch type fuse set(501) determining a signal of a fuse(FUSE) according to the state of the fuse by receiving a signal(init) initializing each part of a semiconductor memory device, and a switching device(502) receiving each output signal of the latch type fuse set and a row address signal(gax) indicating a specific X-block and switching a path corresponding to their signals. A latch circuit part(503) latches an output signal of the switching device a signal(rad) activating a corresponding bank and a corresponding bank precharge signal(pcg).
