Abstract
Consuming current must be reduced in each operation state of a semiconductor device which operates in synchronized with an external clock signal. However, in each operation state, for satisfying the stability of an operation and a speedup, the suppression of consuming current has been performed under difficult circumstances. For solving this problem, a clock generation circuit generating an internal clock signal based on an external clock signal is activated during a specific time period when a clock synchronization circuit is in a state of inactivation.
