DLL circuit and method of controlling the same
摘要:
A DLL circuit includes a buffer control unit configured to detect whether or not a DLL power supply exceeds a reference level and output a buffer control signal. A clock buffer buffers an external clock to generate an internal clock when the buffer control signal is enabled.
