摘要： A semiconductor integrated circuit includes a CMOS circuit operated on a voltage of a first voltage level to set an output node thereof to a voltage of the first voltage level or a reference voltage; an output circuit for controlling supply of a voltage of a second voltage level which is higher than the first voltage level to a signal output node; and an isolation MOS transistor having a current path connected between the output node of the CMOS circuit and the signal output node and a gate connected to receive a control signal. The output node of the CMOS circuit is set to the reference voltage with the conduction resistance of the isolation MOS transistor kept high after the lapse of period in which the voltage of the second voltage level is kept supplied to the signal output node. After this, the conduction resistance of the isolation MOS transistor is reduced in response to the control signal.

摘要： In a nonvolatile semiconductor memory device, a wiring layer is connected between a power source and a memory cell. Resistance of the wiring layer is larger than the on-resistance of a load transistor, so that the load transistor substantially determines the load characteristic. Therefore, the load characteristic curve is more gentle in inclination and more rectilinear in shape. This makes the data writing operation stable against a variance in the channel lengths of manufactured transistors forming the memory cells.
