Abstract
There is intended to provide a semiconductor integrated circuit device capable of lowering the power consumption during data-write operation, enhancing operation speed, and reducing noises for stable operation. In the semiconductor integrated circuit, an active signal ACT to be inputted to a sense amplifier signal circuit SC is latched by a command latch circuit and outputted to a terminal N . The terminal N outputs a control signal EDC via a timing adjusting circuit. The control signal EDC works to output a sense amplifier activating signal LE via a timing adjusting circuit and output buffer circuit and at the same time, the control signal EDC is outputted to a column switch signal circuit CS . From the Column switch signal circuit CS , a pulse signal is outputted via input of a control signal ACL, a pulse output circuit, and a terminal N . In a logical circuit, AND processing is conducted between the pulse signal and an inversion signal of the control signal EDC . Through a decode circuit, a resultant signal is outputted as switch signal CL, or CLM.
