Semiconductor apparatus for controlling a frequency change of an internal clock

摘要

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.

1. 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 frequency change end signal to designate the completion of a mode for changing frequencies of the internal clocks; and a command generation block configured to receive a command and generate the setting command in response to the frequency change end signal and the mode register set signal.
