Abstract
A synchronous semiconductor memory device satisfying the CAS function requirement of JEDEC is provided. Through command input pins and address input pins, external command signals and address signals are applied. A command decoder decodes the applied command signals. A write command latency control unit, a read command latency control unit, and a column address latency control unit delay a write command, a read command, and a column address signal, respectively, for a time period equal to N/2 times a clock signal cycle in response to a latency control signal. N is an integer equal to or greater than zero, and the latency control signal is activated in response to a value set in an extended mode register set.
