Abstract

PURPOSE:To obtain a memory circuit which is not affected with noise causing erroneous motion, by using an MOSFET highly effectively. CONSTITUTION:A ratio circuit comprises transistors TRQ13 and Q14, and a TRQ12 is arranged between bus lines. The signal phiB which obtains an external driving signal through a buffer 10 and a delay circuit 11 is applied to the gate of the TRQ12. As a result, the potentials of data bus lines RB and RB' are reduced to a level lower than the potential of power supply. Thus the effect of noise is eliminated since the noise only affects the ratio circuit although the noise is caused in the lines RB and RB'.
