发明名称 Internal voltage generator and internal clock generator including the same, and internal voltage generating method thereof
摘要 An internal voltage generator that generates an internal voltage for a Delay Locked Loop (DLL) and an internal clock generator including the same, and an internal voltage generating method for a DLL. The internal voltage generator includes a standby voltage generator that generates the DLL internal voltage as a reference voltage level, a controller that generates an active control signal in response to a power-down signal and an active signal, and an active voltage generator that generates the DLL internal voltage of the reference voltage level in response to the active control signal. After the power-down mode is ended, the active voltage generator is additionally operated during a predetermined time when the DLL is initially enabled. It is therefore possible to generate stabilized DLL internal voltages.
