Abstract
A synchronous semiconductor storage device includes: an internal clock activation signal generation circuit for generating an internal clock activation signal cke_c and a latch signal cke based on a system clock signal CLK and a clock activation signal CKE each having a series of pulses; a CKE latch clock control signal generation circuit for generating, based on the internal clock activation signal cke_c, the latch signal cke , the system clock signal CLK, and the clock activation signal CKE, a CKE latch clock control signal cke_x which controls activation/inactivation of a CKE latch clock signal, and an internal clock signal generation circuit for generating an internal clock signal clk_in based on the internal clock activation signal cke_c and the system clock signal CLK, wherein stored data corresponding to a plurality of external signals including a control signal and an address signal are transmitted in synchronization with the internal clock signal clk_in.
