PURPOSE:To prevent the destruction of memory cell information by constituting a word line monitor of the same meterial as a word line and making a signal to depend on the signal of a word line driving circuit obtained through a monitor into the input signal of a balancing circuit. CONSTITUTION:A signal outputted from a word line driving circuit 9 is inputted through a terminal 10 to word line monitor 21. The monitor 21 is formed by the same material as a word line 3. The monitor 21 essentially functions as a delaying circuit displayed by a resistance Rx and a capacity Cx, the output of the circuit 9 is delayed, and inputted to a sense amplifier latch driving circuit 12 and a bit line equalizing signal generating circuit 25. The circuit 25 transfers the output as a bit line equalizing signal An to to a balancing circuit 26 as the input of an AND circuit 24 together with a signal inverted a signal from a resetting signal A and the monitor 21 with an inverter 23. Thus, the destruction of the information of a memory cell 4 can be removed.
