Abstract
A semiconductor apparatus includes a clock frequency change block configured to output a plurality of internal clocks with different frequencies by dividing a frequency of an external clock in response to a mode register set signal and a setting command to enable the plurality of internal clocks to be outputted, and generate a flag signal to designate the completion of the output, and a command generation block configured to receive a command and generate the setting command in response to the flag signal and the mode register to set signal.
Claims20
A semiconductor apparatus comprising:
- a clock frequency change block configured to output a plurality of internal clocks with different frequencies by dividing a frequency of an external clock in response to a mode register set signal and a setting command to enable the plurality of internal clocks to be outputted, and generate a flag signal to designate the completion of outputting the plurality of internal clocks;
- and
- a command generation block configured to receive a command and generate the setting command in response to the flag signal and the mode register set signal.
A semiconductor apparatus comprising:
- a clock frequency change block configured to generate a plurality of internal clocks with different frequencies by dividing an external clock in response to a frequency change signal which allows a mode for changing a frequency of a clock to be entered and a no operation command which sets to allow the plurality of internal clocks to be generated, and generate a frequency change end signal to designate the completion of the mode for changing a frequency of a clock, in response to the no operation command;
- and
- a command generation block configured to receive a command and generate the no operation command in response to the frequency change signal and the frequency change end signal.
