Abstract
Disclosed herein is a semiconductor memory device for reducing an unnecessary current consumption occurred in an idle state or an active state. The semiconductor memory device includes a driving clock supply unit for supplying a driving clock during a read or a write operation of each bank; a delay unit for generating a read address or a write address in synchronization with the driving clock by delaying an address by a predetermined time based on one of an additive latency, a CAS latency and a combination thereof; and an output unit for latching the read address or the write address to output the latched signal as an internal column address.
