PURPOSE:To attain low electric power consumption, small capacity and low cost while making high-speed operation possible by stabilizing the circuit operation, by providing a dynamic sense amplifier with a write-only circuit. CONSTITUTION:One digit line connected to dynamic digit sense amplifier SA is connected to an I/O bus via switching circuit S controlled by line decoder Y. Driving circuit W is provided which operates with a write signal to memory cell MC to generate an output of a high potential with an input at a low potential and to output a low potential with the input at a high potential (or increase its output resistance). Then, the digit line connected to input switching circuit S of driving circuit W is connected to the digit line which is not connected to switching circuit S at its output. Therefore, stable driving operation is carried out. |
