ABSTRACT:
In the semiconductor memory device which has nonvolatile memory cells, the bit lines which are typified by high capacitances, are isolated from the input/output nodes of the corresponding sense amplifiers during the amplifying operation of the sense amplifier. A flip-flop circuit, such as a CMOS latch circuit, is used for each of the sense amplifiers and a switch circuit is connected between each input/output of each sense amplifier and the data (bit) line associated therewith and is turned OFF immediately before or after commencing of the amplifying operation of the sense amplifier. During the amplifying operation of the sense amplifier, the data (bit) line, having a large parasitic capacitance as a result of being typically connected to a large number of nonvolatile memory cell transistors, such as of the single transistor type having both a floating gate and control gate electrodes, is electrically disconnected (electrically isolated) from the sense amplifier.
