Abstract
Provided is directed to a circuit for generating a DQS signal in a semiconductor memory device which includes: a DQS data generation unit for generating a DQS preamble signal and a DQS data, signals earlier than a CAS latency; a DQS output control signal generation unit for generating a control signal to drive the DQS preamble signal out before the CAS latency and to drive the DQS data out after the CAS latency; a DQS driver for driving the DQS preamble signal and a rising data of the DQS data from the DQS data generation unit according to a rising clock of the DQS output control signal generation unit, and driving a falling data from the DQS data generation unit according to a falling clock of the DQS output control signal generation unit.
