ABSTRACT:
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.
