    摘要： Herein disclosed is a semiconductor integrated circuit device comprising a SRAM having its memory cell composed of transfer MISFETs to be controlled through word lines and drive MISFETs. The gate electrodes of the drive MISFETs and the gate electrodes of the transfer MISFETs of the memory cell, and the word lines are individually formed of different conductive layers. The drive MISFETs and the transfer MISFETs are individually arranged to cross each other in the gate length direction. The word lines are extended in the gate length direction of the gate electrodes of the drive MISFETs and caused to cross the gate electrodes of the drive MISFETs partially.The two transfer MISFETs of the memory cell have their individual gate electrodes connected with two respective word lines spaced from each other and extended in an identical direction. The region defined by the two word lines is arranged therein with the two drive MISFETs and the source lines.The source line is formed of a conductive layer identical to that of the word line. The individual data lines of the complementary data line are formed of an identical conductive layer which is different from that of the word line and the source line. The identical conductive layer between the word line and source line and the complementary data line is formed with two word lines: a main word line extended in the first direction identical to that of the word line and source line and used by adopting the divided word line system: and a sub-word line used by adopting the double word line system.

    摘要： A SRAM of complete CMOS type having its memory cell composed of six MISFETs, in which a pair of local wiring lines for connecting the input/output terminals of CMOS inverters are formed of a refractory metal silicide layer formed over a first conducting layer constituting the individual gate electrodes of the drive MISFETs, the transfer MISFETs and the load MISFETs of the memory cell and in which a reference voltage line formed over the local wiring lines is arranged to be superposed over the local wiring lines to form a capacity element. Moreover, the capacity element is formed between the local wiring lines and the first conducting layer by superposing the local wiring lines over the first conducting layer. Moreover, the local wiring lines are formed by using resistance lowering means such as silicification. In addition, there are made common the means for lowering the resistance of the gate electrode of the transfer MISFETs and the means for forming the local wiring lines.
