Abstract

PURPOSE:To eliminate the effect of noise, by applying the lowered voltage portion caused by the capacitive coupling to both input/output lines. CONSTITUTION:A data is read out of a memory cell 26, and O is read out of a cell connected to the same word line 25. In that case, the noise caused from each bit line and by the capacitive coupling is connected to an I/O line 20 through a capacitance 18, and to an I/O line 19 through a capacitance 38 respectively. The number of the capacitive coupling is equal to secure the same level between the both I/O lines. Accordingly an output sense amplifier is driven without requring queuing time. Thus, the data reading time for a random access memory is accelerated.
