Abstract
【解決手段】内部クロック発生回路2が一対のパルス発生回路21A,21Bにより外部から受ける外部クロック信号CK,/CKの動作周波数の、二分の一の動作周波数を有する内部クロック信号CLKB1,CLKB2を生成し、例えば読取りコマンドラッチ回路3で一対のラッチ回路32A,32Bが「1/2」の周波数で動作することにより、高周波動作の際のラッチマージンを拡大することができる。従って、これを他のコマンド、アドレス、またはデータにも適用できる。また、内部クロック信号CLKB1,CLKB2をワンショットパルスで生成することにより、セルフリフレッシュモード等で外部クロック信号が停止した場合には内部クロック信号がリセットされ、装置は誤動作することがない。
