Synchronous semiconductor memory device for reducing power consumption |
摘要 |
Disclosed is a semiconductor memory device capable of reducing power consumption by employing a DLL drive controller. The semiconductor memory device includes: an idle state detector for detecting an idle state that all banks are precharged; a delay locked loop (DLL) for synchronizing an internal clock with an external clock; and a DLL drive controller for controlling the delay locked loop in response to an idle state detection signal outputted from the idle state detector and a delay locked signal outputted from the DLL.
