Self-refresh controlling apparatus |
摘要 |
A self refresh controlling apparatus for use in a semiconductor memory device includes a delay unit for delaying the clock buffer enable control signal by a predetermined time and an internal clock signal activation controller for controlling activation of the internal clock signal by logically combining the internal clock signal with a control signal generated under control of the delayed clock buffer enable control signal from the delaying unit and the internal clock signal in order to prevent mis-operation due to the internal clock signal generated late in completion of self refresh operation.
