Abstract
A pulse generation circuit ( ) generates a pulse signal (S ) of “L” with a rise of a clock signal (CLOCK) as a trigger. A latch circuit ( ) changes a latch signal (S ) fry “L” to “H” on the basis of the pulse signal ( ) of “L”. Inverters (G , G ) output a signal (XDEC) on the basis of the latch signal (S ). Even when the generation of the “L” pulse of the pulse signal (S ) is terminated and the pulse signal (S ) returns to “H”, the latch circuit ( ) is in a data holding state to sustain the latch signal (S ) of “H” during a period while the signal READY takes “H”. With this constitution, it is possible to provide a semiconductor integrated circuit having a control unit which can output an operation control signal in synchronization with the clock signal without being constrained by the time length of “H” (“L”) period of the clock signal.
